I was reading through this thread again, I can't believe that I skipped over this part! That's what's wrong with so many driver's ed schools these days. We have a 911 Driving (cops make it extra special apparently, so pretty high price) & a Go Driving school. Those guys just go into local neighborhoods and call it good. Those guys freaking suck! I went through a driver's school where it wasn't a major name that people are familiar with. The guy that ran it was the only guy there, had only 1 car, did classes all day, and did drives with the students. But the way he did the drives were cool. We had to do 7 drives, each an hour long, but he'd take us through city roads, country roads, mountainous roads, highways, freeways, & even parking lots! He made sure that we knew how to drive everywhere with various speed limits.
But I agree with Z34, it'd be best to teach new drivers (or those that need the lessons) how to work both automatic & manual; rwd, fwd, & awd; as well as proper maintenance, and various emergency maneuvers. I also think that it'd be a great idea if you did classes during the winter, and it snows heavily, teach them how to do snow chains, and let them get used to driving in the snow so they don't chicken out of driving in the snow at all. Same with heavy rain & wind. At least my mom is too scared to drive in those conditions...
