You have to drive 1km as fast as possible
The rails mark the start

Try to make a simple car out nothing else then a
Power supply
Two wheels or wood cylinders
Two motors
Cables
And all basic mechanical and electronical parts
And cam targeter

Robotics and rockets arent allowed
Try to reach the highscore
If you do post your vehicle to the others
Good luck

Ps your wheels have to hit the first layer
