And found it again on youtube of all places :P
I'm sure many of you have seen this but it's a pretty funny "vs." video:

HOLY SH!Ti

hahaha nice find.

You'd better have serious BAWLS to ride that thing.

Or just be effin' crazy.

and the guy riding the scooter doesn't have any protection except a helmet......wow

that's ok about the helmet, a fall at 15mph won't do too much damage because that's probably the max speed he hit on the scooter.

funny as hell though.

23,000 RPM!! Hate to redline that thing!
