Flat Track Gravity Research (BEAMNNG)

I ran the default truck down a flat track (starting from stand-still), decreasing the gravity (starting at -20) by one each time until I reached -5 (past this point cars start to float off track). Here are my results:

From this data I can conclude that gravity has little affect on speed or acceleration on a completely flat track. However, -11 seems to be the optimal gravity here as it took the least amount of time for the car to reach the goal. Come back later for more pointless BeamNG research!
