Perhaps there is someone near by he can ride with. Instead of driving he can contribue to his rides gas money.

I used to do this all the time in school because even though I had my own car, my parents would not allow me to get my license. I didn't get it until shortly after I got married (at 18).

While I did drive on just a permit, my husband and I understood the consequences of my actions, and I think I only drove with just a permit 4 times. As soon as I was able to get my license he took me to the DMV and I walked out of there with it.
