We are 5200 miles into a 7500mile road trip around the US, and just twice we have encountered sever braking from autopilot. On each occasion it was on a straight piece of interstate, I10 westbound, and I40 eastbound, and in both cases, the sun was ahead of us casting a very dark shadow of the bridge onto the road. The braking was so severe - i.e dropping 25 to 30mph as fast as it possibly could, that I am fairly sure that if the motorcyclist who was following me had not turned off at the previous exit, he would have run right up my trunk on I40. Is this a common problem? For the rest of the trip I will be leaving AP whenever I see a bridge, then turning it back on afterwards.
On a less important note, on both of the Interstates mentioned, there are very long stretches that are dead straight, and although I hold the steering wheel with both hands at 10 to 2, quarter to 3, or 20 to 4, I get the flashing white reminders at regular intervals. It would be good to see an upgrade that extends the interval between warnings for dead straight roads... just a thought!
