Just installed it and tried it. One part is cool, one bizarre …
The cool part is driving out of the town of Middleburg on two-lane Route 50. I activated AP and set speed to 60 in a 25 mph zone. The car first held to 30 (showing a yellow triangle indicating the speed restriction was on) then raised speed to 40 just as it passed the 35 limit sign, raising it again to 55 while passing the 50 limit sign. Right after that point the road widens to a divided highway with a grass median. The warning went away as soon as the white lines appeared and the car accelerated to my 60 mph setting, 10 over the 50 limit. The divided highway lasts a little over a mile, and is basically there to facilitate passing. After that the road narrows back to two lanes. AP continued at 60 for several seconds on the two lane road, but as soon as double yellow turned into dashed yellow the restriction warning came back on and the car slowed fairly sharply to 55, once again 5 over. So restrictions may be annoying in principle, but having the car manage speed while leaving (and I presume entering) small towns is pretty cool. Having 50 or 55 mph two-lane roads that slow to 25 going through little villages is quite common around here. I wish the restriction was 7 mph over instead of 5, since that’s what most cars here do, meaning you would not seem to others like like a slow car, but I can see how Tesla’s offering a 7-over restriction would be fairly random. Oddly, there were no nags on my trip, but I touched the wheel on this test more than I ordinarily would. I will test 7.1 on an interstate this evening.
The bizarre part was using the summon feature to park in my garage. It worked in the sense that it drove near the closed door, opened it with Homelink and drove in, but entering the garage the wheel began cranking and the car ended up parking with a sharp leftward skew (I use the right space in a two car garage). The problem was that because of the odd shape of the garage (deeper and wider on the left side) and shape of the driveway, my wife parks her car skewed to the left in the left bay. Looking at it, the MS exactly matched the skew of her car, so the two were parallel. I wanted my car to be parallel to the right-hand wall of the garage. It took me a while to manually get the MS back out because the tight garage door and the curb to the right just outside the door kept setting off the proximity alarm. The car kept shifting from reverse into park, apparently thinking I was going to hit an obstruction. I managed to ease the car out, but had to put it in gear several times. So summon doesn’t seem suited for my particular circumstances.
