I have to point out, a few years ago, after a great number of accidents/other issues with truck drivers, a teacher from Ferrari said, in a hidden shadow interview, "You see these truck drivers and wonder where they got their licences? That's Ferrari.".
I know that Ferrari is the school we most associate with this area, but I hope there will be more responses, because I need a recommendation also.
I'll also point out, most driving schools teach you to move the car around; only experience, and hopefully a passenger with a lot more experience, can really teach you to drive. You don't actually have to take any lessons to get a license.
