SUVs/big cars in general, and people who simply don't need a big monstrous car like that and quite often are incapable of driving or parking them properly.
The thought of the Mum and her Chelsea Tractor springs to mind; with mummy dropping off the kids at school and doing a bit of shopping at Waitrose in some monstrous big car that she really doesn't need.
Or some pencil d1ck guy driving around in some giant motor because he thinks it makes him look like Arnold Schwarzenegger.
While that is all just (usually) a mere irritation, it's much more serious than that...
"On average, SUVs consume 20 per cent more energy per kilometre than a medium-sized car.
The increase in SUVs in 2020 led to a rise in oil consumption that cancelled out the effect of electric cars"

In essence, SUV drivers are totally negating the benefits from environmentally friendlier alternatives.
There has also been research that suggests that SUVs are involved in a higher number of car crashes, which has often been put down to more reckless driving simply because they feel safer in their monster car.
Plus a pedestrian, or other driver, has a higher risk of dying when involved in an accident with an SUV than if it was a standard size car.
