Also remember that his wheel size is not stock so his speedo is off.

Also since his wheels are bigger than stock his top speed would increase but his bottom end acceleration will suffer.

I estimate that on an open road with the wind either idle or helping him he can achieve that speed. He probably would need some space but it would be possible.

Hes probably a retard too simply because I bet he has to much downforce from the wing at 142 to control the car if he needed to react and he prolly has H-rated tires too... smart kid I am sure.
