A few thoughts on Nav and AP after two days of driving. - Nav seems much better. It doesn't do ridiculous things like unnecessary SC stops or taking you back to the SC you just left. So, much improved on this. It is still overly (dangerously?) optimistic though and wanted us to drive 190 miles direct to the next SC instead of a 40 mile longer route with 3 SC's available (5f, 700 lbs payload). Tesla needs to determine weather and payload before making routing decisions. Ben and EV Trip Planner 1, Elon and Tesla 0. Tesla really should be able to do much better. This baffles me. I would also like to see hyper accurate SC locations. Knowing that somewhere within a 600 acre mall and it's parking lot there is a SC is nice but can still take a while to find. 7.1 does seem better on this but still not fully there. - AP much improved. There were only a couple of instances of it trying to take exits. Very much appreciated. Overall does a much better job of seeing lane lines and doesn't weave as much within the lane. BTW, we had an incident with 7.0 (2.9.77) the other day while driving on an interstate with good lines and AP indicating that it clearly saw both lines. Our car suddenly lurched left, jerked back hard right, then left, ... this within perhaps a second before I took control. Very scary and no cause that we could tell. Enhanced Visualization, showing vehicles in adjacent lanes, is good but inaccurate. It shows the vehicles farther away than they really are and misses about 20% of vehicles. A vehicle that we are passing and overlapping a few feet is indicated as still having maybe 10-15 feet of gap before beginning to overlap. What would really be helpful is to show vehicles coming up from behind but it apparently can only see vehicles to the front not sides or back. Moving a lane to the left is worse than 7.0 (moving a lane to the right seems to work fine). Numerous times it would not move over and for no good reason that I could see so after having the blinker on for a bit I'd have to do it manually. This was a problem about 30% of the time. Worse, on one occasion when I blinked to move over there was a car in my blind spot and AP started to change lanes in to the other car. Fortunately we avoided a collision. (non Tesla issue: I learned to drive in Europe with my mirrors much farther out than most Americans so my blind spot is really tiny and this vehicle really surprised me as it's the first time in probably a decade that this has happened). Another 300 miles today.
