Don't get me wrong, there are choices made at each stage of escalation, and often all that's needed is to show up to court, dressed in your sunday best and respectfully explain situation to the judge, and the chain can be broken, but being poor leads to a lot of suboptimal decisions that could make it difficult or impossible to deal with any of this until there is no choice, and a felony conviction often ends up as the escalation that can't be putoff any longer.
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.
