In amusement parks you get a much smaller selection of the population than on the street or even at an airport. People who don't enjoy thrill just have no reason to visit them at all.

Accidents happen, when these mechanical constraints physically fail, not when a computer makes a wrong choice because it failed to detect an obstacle or similar.
