But for the sake of argument, let's say you shutter your car. You can spend a ton of time walking to, and waiting on, public buses, time you can't use to study for a degree, or be with your kids. Maybe you rely on a friend's car, but then you miss out on last-minute shift opportunities, and your friend's transport problems become your problems, too, so if they're sick, you miss a shift and risk getting fired.
You're so out-of-touch, I'm surprised you didn't just say "Let them Uber to work, then."
I'm sorry what alternative are you offering? We live in a society where driving is most necessary for those who can least afford it. I think you may grossly misunderstand how difficult life is for people struggling to get by.
You are right, that poor choices can lead someone to a scenario where there are no good choices though. Most of this chain can be broken by just taking some time to take care of their life, but that is not always as simple as it sounds. Right now I personally have societal+familial+work obligations that total 17+hrs daily and I'm lucky to get 6hrs sleep, 3 uninterrupted. I am not poor, and I'm lucky to have a very flexible job, so I could take time to deal a minor fine so it didn't escalate past early court escalations, but I'm not sure I'd be able to trivially take time off to deal with a court appearance if I had a more demanding job, I don't have a lot of flexibility elsewhere to borrow from.
Never forget that it's easy to judge someone's actions from outside, but in their same mental state and reality constraints, you may make the same decisions.
(Regardless of which nation, obviously.)
