Insurance seems to be the reason for most of the suspensions. I don't have a ton of sympathy for driving without insurance, but it seems quite likely that there is a feedback cycle of punishment here that could probably be improved. Like it can be harder to get insurance once you've been caught without insurance, and there might be additional fines involved, and once you get your license suspended there's often more steps to go through to resolve that as well.
The goal of the system should really be to get everyone insured, and I suspect there are people who don't just have financial problems resolving this but also a hard time navigating the bureaucracy.
It's probably because there are people so marginal and enforcement so lax wherein you have to get pulled over to get caught that it may make economic sense to skirt the system this way. You could make it hard to pay taxes on a car or keep owning it without also getting insurance on it to curb this. Cars with no current plate are pretty noticeable.
