Pretty cool, one thing I thought missing was a peelout effect.
Also, I took the liberty to fix your highscore data, don't know if he was cheating or not.
Check your pms because you should update to prevent that.
Edit*
Also, there may be an error in your cscript, one score had the name doubled up. Possibly due to the a6 string length saving problem(if they loaded saved game then submitted). Update fixes that.
