90 disengagements on a 50 minute trip (assuming you drove 60MPH on average)? That's a disengagement every 30 seconds or so.
What were your common issues for disengagement?
Minimal lane change ON. Wipers OFF - no matter, still dry wipes.
1 - Trying to go 25mph in a 10mph zone.
12 - Trying to drive in left (oncoming) lane, while meeting traffic.
1 - Trying to pull onto highway with no acceleration / merge lane and 75mph traffic with no where near enough gap time.
2 - Met car on two lane highway - it disengaged, slammed on the brakes and stopped.
1 - Met a truck on two lane highway.
1 - Divided four lane highway 75mph. Came up behind semi driving at around 45. Signaled and pulled into passing lane. When around 20 feet from semi, car tried to dive into lane behind semi - that gave me 1/2 second to yank it back into passing lane, which disengaged or would have run into rear of semi.
6 - (est) dove into left lane short U-turn ramp and would have had to make a 75mph U-turn if it figured out the lane was ending and the route was straight ahead.
2 - Car on right shoulder with flashing warning lights. I signaled a change to left lane (courtesy), car did not change or acknowledge lane change - when I forced it, disengagement.
1 - Police car on right shoulder with flashing red and blue lights behind car with flashing hazard lights, same as above.
10 (est) Nav announce in 500 ft, turn right and car dove into far left lane.
12 (est) Nav announce in 1,000 ft, turn left and car dove into far right lane.
On most of these 22, if I had not been hyper alert, it would have slammed into the car in the blind spot, because there usually was one.
Tried to turn into parking lots at 55 mph, both hard left and hard right.
Usually there would be a few of trying to turn into the oncoming traffic lane, but there didn't happen to be any today.
That's the best that I can recall. I really want to try getting a passenger to record them for the sake of accuracy.
