I don't think the US consumers are buying the bigger SUV/trucks because they are safer. At best it might be a minor contributing factor. It's primarily a status/identity thing.
n=1, I dated a low empathy woman who specifically drove a Chevy Tahoe due to mass for safety reasons and transporting her only child in the vehicle frequently. “Good luck to the other driver.”
On the flip side, there's a lot to be said for a low centre of gravity and it's still the case that US "trucks" get smushed by actual trucks (road trains and heavy haul outmass a tahoe).
Great video. She was sophisticated enough to understand the risk profile, anecdote shared to demonstrate that some folks do decision their purchase around winning the potential tonnage battle. Very “tragedy of the commons” that can only be solved with regulation. Otherwise, some will buy big because they can.
