I don't know how most driving schools run but ours about 15 cars showed up so it was race the course and get right back in line. and in about 5 mins you were off again. We did this for about 4 hours straight then broke for lunch and then did it again for another 4 or so. We racked up a ton of seat time but everyone who was on street tires was like god these are getting eaten up. the course was about a 9 outta 10 on the difficulty scale. Stuff like decreasing radius corner and back across into a slalom and right into a chicago box. Very difficult for the rear wheel drive cars. I was 4 wheel drifting around and steering with the throttle at points. Lotta tire squealing and directional changes. Just saying everyone who was on street tires was experienceing extreme tire wear. I was surprised but thouroughly enjoyed it. Best $15 I ever spent.
