Draw your drive

Redraw while driving

Your wheels. Your problem.

Trace around the white hub. Release to fit your new wheels. Smooth shapes roll quickly on tarmac; irregular shapes bounce and catch on steps. Small tyres stay small. Size, grip and ground clearance all matter.

Round wheels love smooth roads. Try lobes when the sand slows you down.

Rigid-body gravity, axle motors and contact physics. If you get stuck or roll over, restart and try another wheel. The drawing pad stays live while you drive.
