Car was fun to drive but this game needed some UI. Speedometer, distance left to travel and maybe a gear shift Image (manly for back up because I wasnt sure I was backing up for the longest time).... also your going the wrong way UI because I am 90% I was going the wrong way for one of my playthroughs.
Also pylons you should be able to hit for free having them rocketing off your car is a missed opportunity. hell you could add to the timer as a small mini game.
