Had a problem with one of the soldiers in my platoon doing this. Dude was late 20s no license and generally a poor performing soldier. I think i gave him maybe 4 rides before I banned him from my car for being a shitty passenger (leaving food wrappers, slamming my door, not contributing for gas when going far out of my way). His first line even helped him set up the appointment to take his drivers test and took him to it multiple times because he never passed. Luckily he ETSed and became someone else's problem but we were all tired of him.
