David’s driving school is very good; sorry, I don’t have contact info, but it’s run by David Dahan in the Main Monsey area (on Highview or Remsen or one of those blocks- don’t remember, it’s been a bit). There are group driver’s ed classes on Sundays (basically all teenagers) and private driving lessons (you get six free if you take the driver’s ed classes, which if you have a competent person outside to teach you to drive is more than enough).
I’ve also known people who liked Dana’s driving school, which is more in the Rt 45 area. Don’t know much about it.
