At least weekly; 3 times today. Still need to compile some more data to know for sure if it is faster overall, but I have never seen 120kw; 118 for sure, but not 120. But 12.1.1 is a keeper for sure. AP1 over the past year has gotten better and better, so yes they are still improving it. A year ago I didn't even bother using autopilot. Not sure if all that data Nettie the neural network supercomputer is aiding in the developing on the AP1 side of things, but after 700km driven today on familiar roads it definitely holds the centre of lane better and ping-pongs less than before. I think it weaved noticably only 3 times today. Usually the wife is demanding I take over because the AP makes her carsick; today I heard no complaints. Even on some highway stretches where painted lines did not exist it did a little better than previously. And when changing lanes one only needs to put the tires into the other lane, where previously (I was on .8.4 after 50.6) you would have to hold the turn signal until half the car was in the new lane or it would snap back into the initial lane. You reading this @bmah ? On a few lane changes I got away with holding the turn signal for 3 blinks, but most of the time 4 blinks of the indicator was enough to successfully change lanes. Previously it was more like 6 blinks. Not perfect yet, and probably never will be, as there was still some unnecessary braking when passing tractors situated in the outside lane around left handers, but I am used to that, anticipate it, and I have my foot handy on the accelerator to override the braking. And yes, over crests the camera cannot see and for some strange reason it still does not incorporate the direction of the road shown in the navigation to steer the car, but maybe some day. And it did completely blow one slow 25 mph 90 degree corner where I had to overtake, but same as before. I don't have access to the large multi-lane highways with overpasses/underpasses, so I cannot comment on the complaints of others with the "fleet" braking. 700 km today and I feel so relaxed and well rested I could hop in it and do it again. I loved this car a year ago, and I love it more now.
