If the wall deflects though, then the car hitting the wall will sustain less damage, which is usually the case.
I've had Dynamics lol.

You should get your money back.
Conservation of energy: If the can of soda bounced backwards after hitting his bike, the force of the impact was greater than the force contained in the moving can of soda. Even if the soda were the fastest moving object.
The fastest moving object doesn't always have the most kinetic energy in a collision either. So you're wrong that a moving soda can will not apply more force on a bike than a stationary one.
