SUVs are basically required in many parts of the US. Or at very least, it's much worse to have a sedan in the snowier and hillier parts of the country. Not to mention towing capacity or the more rural areas where off-road capabilities are important.
This also doesn't account for towing capacity. Most sedans are not suitable for towing a boat, for example.
I assume the ban would exempt commercial operations, but something to bring up as well.
Focus on electric vehicles, not bans on trucks and SUVs.
