Regardless of any safety claims, for that reason alone, I don't see it as a politically viable issue.

1. Fuel economy regulations that scale regressively with vehicle size, that incentivize automakers to build and market larger vehicles that are easier to hit regulatory targets.

2. Rollover and crash worthiness regulations that require thicker A-pillars and more robust roof structure.

3. Towing performance. The large pickup manufacturers are in an arms race to beat each other’s power and towing capacity numbers. This requires a large, upright grille to provide adequate cooling for a large engine.

4. Consumer demand. The idea that marketing is telling people what to buy is silly. People are spending $80k+ on massive vehicles because they like them. Simple as that. The industry puts lot of marketing effort behind vehicles that are flops. They can’t make people buy a product they don’t want.

Disclaimer: I own a huge diesel pickup, along with a Tesla Model Y and a Porsche 911. Why? They’re fun! I use the pickup to tow an RV, but it’s also just fun to drive.

I have definitely noticed the visibility problem though. Forget pedestrians, sometimes entire cars are hiding behind the A-pillar! You have to move your head to the side to clear the blind spot safely.

If you don't know Rollie Williams, Climate Town videos are informative but suffused with a lot of humor to prevent it from being too preachy.

end the idiotic chicken tax and make small trucks and utes legal again

while we are on the topic, full size vans make a lot more sense than "suvs" for most families
