After more than a year, I have come back to this and realized that kilebantick and VZxtrikez08 have valid points. Thanks for pointing it out.
I designed my vehicle with a light vehicle weight in mind. This was partially due to the first version of my vehicle.
The reason mine (as is) stands no chance to lololoer's is because the gears of mine slip. Changing the density of the frame and gears and tweaking the springs helps a lot.
The reason that it shows up as "12/31/1969" is probably because the Unix time of 0 is interpreted as "1970/1/1 0:00:00" and shifted to match the time zone you are in.
