I feel a way to combat suburban hellholes is to at least make it more cycle-friendly in those areas. Big stroads kill any chance of people being able to cycle to stores, I feel a lot of people don't want to have to drive to get to a Walmart, especially in hot months and would probably prefer to bike it instead. There's obviously also the health benefits of people cycling too. For those more lazy individuals, e-bikes and e-scooters are a good idea that can help them rely less on their car too, and are far cheaper to run than a full car.
Eliminating huge sprawling suburbs is a monumental task, but we can at least apply patch fixes for some things at the moment.
Similar experience from a European.
I own a 2015 Vauxhall Adam. It's a brilliant little petrol car, 3 doors, very small and very reliable.
GM canned the model in 2019. It makes no sense to me, if they had stuck a battery in it for an electric version I'd have been sold in a heartbeat.
But no, GM wants to focus on big cars that I don't want. I don't want anything bigger than a 3 door hatchback, I'm only 20 and have no kids, why do I need some massive fuckoff SUV????
