Pretty late to the party as I only just - finally - got 14.8 a couple of days ago. 1 year old (i.e. non-highland) M3. My impressions so far:
- I tried the TeslaVision parking visualisation and lasted less than two days before switching it off. I guess it's an interesting simulation of what it's like to park when legally blind, but I found the shifting vague grey blobs didn't give any confidence that I could rely on them to avoid hitting things, and were more of a distraction than anything. I'm also not convinced it actually works very well. I had a case where I stopped in front of my driveway gate at night, which it myopically detected as a thin grey blobby line, got out of the car, opened the gate, got back in and drove forward and it though the gate was still there, warning me to STOP as I drove through the grey line where it had been. (I tried to reproduce this the next night but I couldn't because it did the other thing it's been doing since a few updates ago, which is often if I get out of the car and then get back in again soon after, as I do every day to open the gate, I sit back down to find the screen has gone black. I can put it in gear and drive forward, with a black screen, and it takes several seconds before it comes back to life.). Anyway, I found it a relief to get back to old-school visualisation and USS. I do get the forward wheel track lines now though.
- The updates to the visuals are nice - lots more cars, traffic cones and wheelie bins showing, as well as brake lights and indicators. Unfortunately it seems to get the brake lights and indicators constantly wrong. A couple of times it's thought a car in front has been indicating when it hasn't, presumably the LED tail light strobing thing. This morning I was driving in the early morning light and it constantly mistook tail lights for brake lights on the cars in front. Don't get me wrong, machine vision is hard and I'm incredibly impressed with how much stuff it's detecting and tracking around it in real time - but I can't fathom why they'd they turn on a new visualisation if it just reveals that the thing in question just doesn't actually work properly. It undermines confidence and leaves me feeling like we're further away from self driving than I thought. Assuming the intent is to use the brake light and indicator information to inform decision making it's not good if it regularly think cars are signalling or braking when they're not.
- matrix headlights, on the other hand, have exceeded expectations. This is probably the main thing from the update that I was looking forward to and hoping would work well, and so far I'm impressed. Driving down a windy road in the dark it's impressive to see the beam pattern constantly adjusting to notch out the car in front and any oncoming vehicles. As someone who gave up on auto high beams a long time ago I'm feeling optimistic that this is something I can leave on.
