Comment Car Safety (Score 2) 327
Engineering car safety is notoriously hard. Almost every design choice is a compromise of one thing or another
Crumple zones make cars a lot safer without adding significant weight and reducing fuel economy. It means, though, that even minor collisions can total a vehicle, or cost multiple thousands of dollars to fix.
The most dangerous accident for a car is a rollover. One of the reasons is the roof can cave in and hit your head, injuring or killing you. One way to fix this is to reinforce the roof, which adds weight high on the chassis, and makes rollover accidents more likely, increasing the likelihood of other injuries from rollovers.
Lastly, you have legal pressures complicating everything. If you go ahead and reinforce the roof, you'll be sued for increasing the likelihood of rollovers. If you reduce reinforcement and the roof caves in, you'll be sued for that.
