Yes, there are legitimate uses. However, trucks and SUVs account for 80% of car sales in the US. 80% is NOT representative of the number of people who actually need a truck or SUV.
Trucks and SUVs kill more people, because they are bigger and heavier and have less visibility. They run over more children, because the hoods are so high you could lose track of a whole kindergarten class standing in front of them. They are more efficient than they used to be, but still drastically less efficient than a sedan or station wagon.
I don’t judge someone for having different tastes. I judge someone for letting their aesthetic choices cause them to do more harm to the planet, and endanger more people, and risk the lives of their own children (because that’s who they’re most likely to run over because they can’t see them).
If you need a truck or SUV for your job or because you actually haul a lot, or maybe because you have accessibility needs for a bigger vehicle, great. Enjoy. But that is NOT 80% of people.
