Have you ever met someone who spends all their spare time trying to
boost the output of a car's engine, or has blown up at least opne engine
while pushing it too far? I've met plenty of people who build race cars
and they will blow an engine before they will let another car win.

Whether the last part is foolish or just the cost of doing business
depends on the payoff for winning and what it costs to appear and enter.
Blowing an engine, especially one that is heavily worn (in some worlds
it takes only one race to ruin a drive train), might be a drop in the
bucket next to losing the race. Strange as it seems, some people race
cars for a living.
