A rider who only accelerates will never be able to stop, going faster and faster until his head literally explodes.

The question is, what happens to that extra energy as you cruise at a given average speed, braking negligibly or not at all?
He still carries that kinetic energy. If his speed never changes it will be constant. When he brakes his brakes will turn it into heat and so get a little hotter. Alternatively, when he starts uphill he will coast further up the hill to gain more gravitational potential energy.
