probably high teens, it really depends though... are you good at following the racing line? Wait is this a track with corners or just a straight line? Because straight line in my honest opinion are a waste of time and I rather get the same rush in a go kart or something..
that's why go kart racing is the bomb, its a twisty track, feels very fast (although top speed is 30mph) and no wear and tear on your own car
and only 10 bucks a race (10 laps, if your pro you get 30 seconds per lap although my best was 32)
annd the best part go karts are rear engine drive, so its drifting heaven
and boy the steering really tires out your arm after two races.
