Lori, my son does not have his drivers license but he at one time lived in transitional housing close to the school where he worked in the cafeteria and rode a bike to work. We did pay for the bike to get him started. It was not that expensive. We always advised him to find housing that is on a bus line. Actually, one reason living in our home will not work (other than we are done with that) is we are not on a bus line, and it’s too far and dangerous to ride a bike (or walk) to work.
He is currently living out of state and has a decent job, although I don’t know how he is getting there. In the past, he has had to pay someone to drive him.
Your son can do the same things. These are natural consequences of his bad choices. Let him figure it out.
You are doing great and I truly get what you are going through. Love and hugs
