these tracks should be relatively easy.
That's the problem. The current track isn't. Ramming and buggy physics near the start tends to take out one to seven players in my experience (that seven was a real whopper), lagspikes and more odd physics take out a bunch more on the jumps. By the time they're halfway through, there's only like five people left, usually less, and the remainder of the course (specifically the trees and the three-path sections) take out most of the remainder.
And people like Filipe and Darren who always make the shortcuts and rarely if ever fail on them tend to ruin the fun, but that's not something that you can just fix like that.
Also, add something to autokill players in the spawn room when the spawndoors close again. Maybe have the entire spawn section's floor give out. It would ALSO prevent abusers from respawning other vehicles in the middle of the race, so two birds with one stone right there.
