I appreciate the effort, but there are some improvements I have to point out.

Many of the parts look improperly positioned that creates an uneven (artistic) balance. Use the grid tool to create a better balance and to center parts.
You can make text by making a box. Hover the cursor into the "Text" option and type the desired text at the box. I would recommend making the resolution at least 128 px by using the resolution slider.
I wouldn't recommend using the colors on the top left corner (or as I'd like to call, "basic" colors) and use the HSVA color slides (or the color picker above the sliders). In any and every object, uncheck the "Draw Borders" checkmark, found below the HSVA sliders.
The wheels should have controls. If you hover into the dark cyan box and click it, you are required to select a key (you can click it again to cancel). If you press a key and play the scene, you can control the object by using the axle.
Simulation frequency makes things act more realistic the more hertz you add, at the cost of computer power.
It isn't necessary to change an object's material just to find the right color. Again, use the HSVA sliders and/or the color picker box to find the right color.
This car has decent suspension, good deformation and the visuals are great overall. There are a couple problems i would like to point out.
The axles on the wheels disrupt the visuals of the wheels. I would recommend making it transparent and move it to the "back" (select the axle, hold shift and scroll).
I wouldn't use the colors on the top left corner. Instead, use the color picker or the HSVA sliders.
The door should be the same color as the body of the car. To add the outline, use the brush tool, draw the outline in a small size (say at least 0.010) and make the color of the outline black.
I almost forgot to point out that the suspenion is a little wonky. To counteract this, make the spring's strength stronger (between 700 - 1500, depending on how accurate it is to the reference image) and to avoid excess bounciness.
Don't be. We don't hate you; we just don't like your low-effort scenes. We want you to create more complex scenes that will save you time. Algodoo is a physics simulation app, not a place for scenes that have virtually no purpose. There is so much to live for. We just want you to unleash your creativity. Make a marble race, a crashable car, or anything that requires creativity, skill, and effort.
While the scene in general are decent, I would recommend unchecking the "Draw Borders" boxes in any and every object. You should also make the axle (that makes the fan spin) a brake to make it slow down in a couple seconds instead of five seconds. This comment is almost identical as the one i posted in another scene of yours a while ago, and you didn't notice.

For the control thing, I would recommend doing some scripting to add more options.
Use the grid to center parts. I noticed some assymmetry on the center thing on the fan. I almost forgot to mention this.
For the borders part, I would recommend using the tip to other scenes.

And I did not notice about the minute fact. I read the description and I assumed it to be a mistake.
While the structure of the car and the course itself is decent, I cant help, but notice the axles on the wheels being off-centered, causing the car to wiggle. I would recommend using the grid tool to center parts, like wheels, of course.
This could be used as a low-framerate projector or a slideshow tool. I found this out by randomly thinking.

There is, unfortunatly a cause on why the wheels still look uncentered: the suspension is bad

Make sure the springs are also centered on the "suspension box" (don't make the end point to the box too centered, just a bit above the axle) while building cars. To prevent the suspension from being too bouncy, increase damping. Daming reduces the "bounciness" of the springs. You can make the suspension "higher" by changing the "target length" into desired amount.
Thanks for the comment! I used cropped screenshots of each planet's 3d models, move the models to their north pole, and created the significant features of each planet location-accurate (the rest of the terrain is purely handmade). In the developing board, I added two more planets and the Sun, alongside some tweaks on each planet's positioning.
The car is bouncy because the suspension is not centered enough. Use the grid tool to center things.

The car in general looks too rough. Use the polygon tool, hold shift, then hold left mouse and drag the mouse to create perfect lines. Always make the lines correspond on the base image you use to make your car.

I wouldn't recommend using "basic colors" (the colors on the top left corner). Instead, use the HSVA sliders or the color picker to add more variety.
There are a lot of problems in your scenes. Here's my suggestions/how to fix these issues.

There is no suspension in the car(s). Try making a suspension system that is simple. Increase the spring constant to strenghten the spring and increase the damping to prevent the suspension being too bouncy.

You can make axles breakable by decreasing the break limit. The break limit makes an axle break if it reaches such limit. Make sure to make all axles (except the ones on the wheels) brakes and increase the simulation frequency to at least 100 Hz.

The car looks lackluster mainly due to the lack of details in the car. Make sure to add many recognizable details, depending on the quality of the base image. You should use the HSVA sliders and the color picker to have more color variations. The door borders should be black, or slightly darker tha the car's body.

Click at a polygon and select the "Follow" option, and the camera will follow the said polygon. If you want, add an interior and a ragdoll to make the car look even more detailed. The background looks extremely plain in general, why not add content (like buildings and trees) and terrain on it?
what happened to him
I almost forgot this one; Add rims to the wheels for more effort.
Where's the suspension? Where's the rims? I already told you these as constructive critisism. It's in one of your scenes by the way.
The mechanics are okay, but here are things you need to improve;

You can change the colors of the scene. You can use the colors of the top left corner, but I'd recommend using the HSVA sliders and the color picker above them.

In one of your crash scenes, the car itself is stationary. I recommend not using fixjoints and use multiple polygons traced from a reference car image and axles with a break limit. You should also improve your ragdoll by doing more research; the ragdoll is just a couple of boxes with two circles. above the torso.

Making a crashable car comes with risks of failure, but with multiple attempts, you will make a masterpiece. A good crashable car scene may have an interior, a lively scene, a good ragdoll, a suspension, and other optional factors (like accurate scaling, etc)

TL;DR, You should focus on the visuals and make more complex scenes than just a bunch of polygons lying around.
I forgot about these improvements a while ago, and I just realized them.

You can remove the borders by unchecking the "Draw Borders" box on any and every object (unless it's a detail, like a gas cap or a door border). The gaps between the wheels should be filled with a black polygon matching the shape of the car. Don't change the material of the glass panels with the material to get the desired color, simply use the HSVA sliders and the color picker above the sliders to make the panels blue. This should be set for the entire scene, including the car.

Again, don't use the brush tool. Instead, select the polygon tool, and hold the left mouse button to make perfect lines. This should apply to every detail.

The rims are too undetailed and uncentered. Make the rims from a reference image, and center them by using the grid tool.

The terrain looks too rough and when I try to drive through it, it occasionally stops the car due to how inconsistent it is. Use the same polygon tip above and try to make gradual yet rough terrain, or use the polygon tool and make terrain.

Don't use fixjoints just to glue objects into the background/another object. Instead, use the "glue to" tools in the geometry actions section.

Please read the entire message sentence by sentence. I split up the text into sections for easier reading, and you seem to ignore it, probably because it's too long.
Hey there.

First of all, I sincerely apologize for the comment I made in one of your scenes.

Second of all, I've seen some improvements, but there's more work to be done.

The wheel controls are confusing. Don't toggle all of them and the brake should be the down key or the "S" key, depending on what group you're comfortable with. You can override the motor speed limit by simply clicking on the motor speed number and typing a number larger that the limit, say 500, 750, 1000 or more. If you focus on accuracy though, research the speed of the car, use the top speed and try to achieve such speed by testing the car.

You should increase the sim frequency to at least 100 before making the car and when making the hinges, you should set the legacy mode for each and every hinge to 0 for better crash results. Make sure they're brakes too.

Why?
where's the cities? where's the moon?

jokes aside, that is really cool
If you are wondering why I deleted v0.2.2, it's because I've unintentionally reshared the scene on the same preview. This one is a separate upload, so hopefully, I would prevent making these mistakes.

this guy's really cute
This is beyond perfection

10/10
Please elaborate on how the game works. I'm extremely confused on how this game works.
While this scene is a great start for coding computers, I'd also recommend improving the visuals of the scene.

I'd recommend researching computer aesthetics/what they look like in a specific time period to have a better base of what you want your computer to look like.

I wouldn't recommend using the colors on the top left color in the appearance tab. Instead, use the HSVA sliders below the color picker to have more color variety. Uncheck the "Draw borders" box in any and every object for a more aesthetically beautiful look, even if it's only slight. Text resolution in all parts with text should be at least 128.

For logos, I'd recommend using an art or graphic design program(s) to create the desired logo and paste it to Algodoo by dragging the logo to the scene (if the logo is transparent however, and comes up with certain parts separate, simply undo it and keep on going).
/unjoke The mechanism looks cool and adds the sliding effect unlike the sudden stop of mine. I never knew where the problem with the wheels stopping come from until I modified the axles to brakes.

/rejoke this scene is a copy of a copy of that metro train scene that uses thrusters instead of axles
I could really see the effort level up. The control isn't even functional; space is pause for the unmodified controls. Instead, use another key. I'd recommend using the up key, as it's the most sensible key to use.
You do realize that you can change the absoloutely horrible colors by using the color pickers and the HSVA sliders, right?
