This is not a joke. In a pioneering 2015 study people were presented with a hypothetical scenario of a self-driving car about to run over several pedestrians.

When they were then asked whether they personally would buy a car programmed to sacrifice its owner for the greater good, most said no. For themselves, they would prefer the Tesla Egoist.22
