It shouldn't get through...
... but that doesn't mean it's bad, it's actually pretty good. All i'd say is more tracks obviously, less laps, 10 laps is pretty boring, even though they are only like 10 seonds a lap. You could have 10 laps if there were CPU opponents, taht'd be pretty cool. More cars too, like if you get less than a certain time on each track you can unlock a new car etc.
