Just to add in general, I'm coming from a 2016 Honda Accord Touring (TOTL) which has pretty good, if not outstanding, on-board computer-aided driving which I've enjoyed greatly. It came with:
• Adaptive Cruise Control (ACC) which helps maintain a set car-following interval, and speeds up and slows down accordingly.
• Road Departure Mitigation System (RDM), which is a small forward-facing camera in front of the rearview mirror body housing that identifies common safety markers, like lane dividers and raised pavement markers, and alerts if it detects that the car is about to leave the road.
• Lane Keeping Assist System (LKAS) ensures that if you begin to leave the center of a detected lane without signaling, the steering adjusts ON ITS OWN to keep you centered.
I've been amazed at the accuracy and comfort of these three technologies and used them all the time. That said, there were still "issues" and scares such as on a local road when the car in front of you turns right and you are continuing forward, the tip of his (receding) bumper almost 98% already in the right-hand road triggers the Collision warnings and automatic breaking on the Accord and the car slams on breaks(!) even though the road is clear ahead. This happens every time in this scenario and the car never "learns" or adjusts its paranoid behavior.
On the highway it was a pleasure to drive since when it finds the road markings it does a terrific job staying within the lane and even handles cresting, curves, etc. However it bugs you to tap/jiggle the steering wheel every 70 seconds or so, so it is not really self driving.
My point is the technology is out there. Perhaps Honda licenses/uses MobileEye which can explain why they are seemingly somewhat ahead?
My 2017 Tesla AP2 Model S AWD is due in 2-3 weeks and I'm very much looking forward to owning it and contributing here like all of you have and continue to do.
Hopefully by the time it's here (Northeast) AP2 would be further ahead.
BTW someone upthread (or in another thread) posted that most(!) of the AP2 cameras aren't even live yet (he tested by taping over them one by one to see effect), perhaps that means an exponential improvement is possible once they turn them on?
