To get back to the original post: Bad Guys rarely use cars as deadly weapons. With guns, it's obviously different.
Before the feds got into the act, Texas law allowed a felon who either had served his time or was on parole to keep a gun in his house as a means of self-defense. Self-defense is a human right, as almost every pro-gun poster has stated on TFL at one time or another.
The feds now say it is not, without regard to the violence of any particular felony.
If some dude loses his license for Driving While Stupid, giving him a restricted to-and-from-work DL makes sense. That's when Dudley Doofus is sober and of no potential harm. If he wants to bar-hop, he can take a bus or cab.
In court decisions, as with most other things, there ain't no "One size fits all".
