This is a very harsh take for something that is legal and widespread everywhere across the world (at least Western world).
You have to try really hard to pretend you don't understand why this is happening. It's a race to the top of the safety spectrum, and for good reason. Traffic accidents are among the single biggest sources of preventable deaths and grave injuries, and getting a bigger car is one of the single most important aspects you can control in this equation. It's actually super simple.
If this is truly a problem, and I guess it is, then there should be some form of legislative intervention against it. The people buying them are not the problem, the environment which encourages this is.
