I have no frigging clue why these biker jerks aren’t deafened by their own noise, when they manage to give me a start from a hundred yard away every single time.

They are young and only get a couple of hours of exposure per day so they can do that for a few years before they're completely deaf.

The sound is being pushed out behind them, and in a car it’s further muffled by the interior of the car. Nothing to do with minimal exposure.
