There are too many large, heavy, dangerous, expensive 'cars' on the roads everywhere in the world.
I can drive. I do not own a car, and I have set up my life not to need one (nor nee to fill my brain with rubbish about insurance etc), but I would consider one of these. I could even charge it from my roof or off-grid PV.
I do find it hilarious that my dad's old F150 truck made back in the 1970s is way smaller than modern trucks.
People want big cars, for ego, for convenience, for perceived safety.
The US, for decades now, has laws on the books which make it more cost effective for manufacturers to make big, heavy cars. Look up the light truck exemption.
If everyone drives a huge car, you begin to feel less safe in a normal sized car. This means that even people who wouldn't normally drive a truck or SUV begin gravitating towards them because they don't want to turn into pink paste when a 19 year old phone addicted driver in a Ram 3500 slams into them going 60mph on a residential road.
For instance, what is more likely: people drive large cars en masse because they have fragile egos, or large cars are solving some problem they have, namely they have a lot of stuff to carry around?
As a personal anecdote: after the first kid, I had to ditch my tiny car for something that would accommodate all the stuff that comes with a kid. Now that we have a second on the way, I realize the small SUV we got is too small.
When you were a kid, how big was your parents' cars?
My point is that you can never hope to solve a problem if you don’t even understand the fundamental circumstances that caused the problem to arise. Of course, not every person can know every thing, but it’s a good signal that you might be operating under false pretenses if your argument requires people to act in some derogatory way.
I have a whole separate gripe about people expecting more and more public land for free (a single parking space is worth ~£50k around me and should be rented out for ~£3k/year at market rates), and over two stories could accommodate one person. My house is being bulldozed soon in part because there was no other way to get people to allow increased residential density and stop using three parking spaces per household on average. In an place where my familiy doesn't even need one.
Car advertising seems to be entirely about ego and fantasy, the little that I see. And SUVs etc are far more profitable for them, this again is unemotionally clear. The fact that they are prepared to kill more pedestrians, damage the planet, and be complicit in the theft of public space, all for a quick buck, is the reason for my bile.
