I actually suspect part of the reason people keep buying larger cars is because larger cars are safer and sometimes get better safety scores because in a two vehicle collision a heavier vehicle will experience less acceleration in the crash. Also more space to absorb the impact, increasing the time over which the acceleration happens. This genuinely makes heavier and larger cars safer if they are designed properly and maintain the same braking performance, which is totally possible. However the issue is that a larger car is only a safety advantage if your car is large compared to other cars on the road, so if everyone else also buys heavier cars no one wins and pedestrians, the environment and so on all lose.
