Hi, Im pretty disappointed with V8. A major version update like this should be a quantum leap better than what came before, but in the case of V8, its quite a step back in many areas, and no steps forward, in my humble opinion. 1) the "bigger" map that now requires an extra touch "somewhere near the top" of the laggy screen to get the music, nav, energy menus back, and to see the LTE signal bars, is just annoying. Surely for car user interfaces, anything that reduces the time your eyes are off the road and fiddling with screens is better? So why add the need for an annoying extra screen touch to get the menus to show? And the screen processor is so slow and unresponsive, I find myself touching it a second time to get it to respond as it feels like it didnt take the first time, the lag is so bad. I sure hope thats not the same processor making life and death decisions for auto-pilot! It feels slower with v8 that it did with v7.1. 2) LTE signal much worse. With V7.1 I pretty much always had 3 bars around Santa Ana, CA, now I get a pretty solid one bar, occasionally 2, and the connectivity is correspondingly appalling. The streaming radio stations I listen to in the car are constantly stopping or buffering, and quite often don't even pick up after buffering requiring yet another several screen touches to get the menu bar up, go to the music page, then re-touch the favorite. Even this doesn't always get it back playing again, i guess based on LTE signal. Definitely a step backwards, the V7.1 streaming and LTE worked great. What a shame. 3) Auto-pilot. Its just plain dangerous. The car weaves all over the lane, quite often I found myself all the way to the left of the lane, even over the line into the next lane on some occasions. It drives like a drunk driver. It veered _towards_ a huge truck in the lane to the right of me as I passed it on 91 yesterday. Also I got the sudden slowing down effect similar to other reports on TMC of the "ghost car", but there was no ghost car on the screen, it just slowed down for no reason. If you are on even a slight curve in the road, the sensor of distance to the car in front seem to be looking only straight ahead so if the lane next to you and ahead is clear, causes the car to speed up when in fact there is a car in front in your lane but only just a bit further around the corner. Im not talking about very tight bends here, even a slight curve in the freeway lane had me accelerating towards the car in front and then hard braking when it came "into view". v7.1 AP was a bit clunky in places, but felt way more stable. Ive looked at the release notes, and really I couldn't care less about 95% of the new stuff in V8, literally no noticeable improvement, only steps back. The FWD moved quite fast enough in V7 thank you. These are my top rants. Im sure I will remember more after I hit send on this post. If we are eventually to trust autonomous vehicles with our lives, a major version software update needs to be so super stable, like totally glitch free, and better than what came before. The "user" needs to have absolute confidence in the car's software and systems such that you never have to doubt that it will respond instantly and "do the right thing", whatever that may be. As I have stated, IMHO V8 is a step back in stability and "trustworthiness" from V7.1 and has reduced my level of trust in both the car and the company. It feels like beta code. Where are Tesla's QA folks, and what happen to their quality standards? Or maybe we are the beta testers?
