They could swerve into somebody's car and cause a collision
Following distance should be increased (more distance) when behind a motorcycle because (1) the MC can stop faster than a car, and (2) it could go down for many reasons. Greater distance decreases the likelihood of running over the MC.
A wheel bearing could.
Yes
Elastic collision transfers more energy into motion while inelastic transfers energy into deformation of the objects. Elastic could be called more efficient transfer.
