Awesome demo "simmbad". I dont know about you but the car tire handling characturistics looked a little too freaky for my taste. It just looked like a wet road and a hard turn would kick your tail out pretty quickly.

do you have a version with the "gravity switch" on? 

Thanks for the video simmbad.  I know there are people out there that have used car tires on their bikes.  They need to see these two videos you did to see why that isn't such a good idea.  I know a guy that spent a few weeks in a comma cuz he thought he was saving so much money by using a car tire on the back.  I'm thinking he wished he saw this video first then he probably wouldn't have made that stupid decision.
