Guess what? No lifts, no wheels, no pieces of granite stopping them in the middle of a race. It was just 20+ cars racing around a track.
Seriously, there is nothing worse than racing and then having to stop and wait for a lift to arrive, or stop for a wheel/cog to go around. Races should just be that. Races. Not let's see who is the best at getting onto a lift etc.
It ruins my experience when these things happen. Adventure levels - I have no issue in lifts etc, but please consider races without silly obstacles.
Most of the players I know of are getting this. It makes it all the more rewarding when you win. I'm up against 1,200 cc constantly at the moment. Just upgrade wisely (I'd suggest speed upgrades first) and you'll get there soon enough.
