Part of the issue is that larger vehicles are “safer” for the person driving them, so long as their crash partner is smaller. Larger vehicles are more likely to “win” crashes versus smaller vehicles and
pedestrians, at the expense of being more likely to be involved in crashes and more likely to cause fatalities when they do.
It’s not just about how safe it is for the driver or passengers of the vehicle, it’s about the impact of those design choices on the safety of everyone else on the road.
