This morning, I used it from Ottawa to Montreal. Overall, the journey was smooth with no major faults. However, I did disengage it 3 or 4 times due to my lack of trust. Once was when arriving at a toll, and another when merging for a lane closure.
Additionally, it tended to linger on the left lane for too long after overtaking. On the bright side, it handled orange lights very well—stopping for the first one (as I would), and accelerating for the second one when a vehicle was behind me (also as I would). The highway entry was very impressive, smoothly accelerating to merge without any danger. It also handled stop signs just as I would.
