Doesn't it only take a couple of weeks to get a drivers license in the US?
Assuming that you can find a car to drive, you will take a lap around the block to demonstrate that you can steer, stop and maybe parallel park.
The barrier to entry is pretty low.
If only the US was smaller...
I don’t know much about prison/jail but I do agree it should focus on re-habilitation they should have systems to help you study and get a drivers license while in there for example.
That's a lot for an ex-convict.
