When a fender bender happens today, there are sonic sensors, wiring harnesses, cameras, lidar, radar, and sometimes even more to fix. That hardware helps explain why it’s so expensive to repair what used to be very minor accidents. Collision claim severity was about 10 percent higher for cars with driver aids than for those without. Simply put, when modern cars crash, they’re more expensive to fix. So cars with driver aids are actually saving drivers money overall because they avoid crashes to begin with.
