"Hands-free technology can increase risk by lowering barriers The research team found that cars equipped with Apple CarPlay showed a larger album-release effect on fatal crashes than those without it — the opposite of what most people would expect from a hands-free system. Jena explained: 'CarPlay is something that should reduce issues in the car... supposed to be hands-free, but it does lower the barrier to accessing everything. You can just touch the screen very easily and go from one song to the other, so you're probably doing it more than you otherwise would have.' This is an instance of the Peltzman effect: technology that feels safer can cause compensating behavior that erases or reverses the safety benefit. The decision-shaping implication: when adopting a 'safer' tool, watch for whether it increases your frequency of use, because that can negate the safety gain entirely.
