And this is exactly why I'm not selling my current M3 with USS and stalks. Its backwards to even think Vision will be just as good on on par with USS.I purchased a new MYP in January with the knowledge that USS had been removed. I discussed this with them in the showroom and they assured me performance parity would come - I was skeptical however as I'd seen early results. I was careful to document the discussions and also emailed a few times and received replies. The replies from Tesla referred me to their press announcement and vision "meeting or exceeding" the performance of USS. It very clearly hasn't.
I emailed them again a few weeks ago to ask when we could expect performance parity and noting that the system basically doesn't work at all after heavy rain, with road film or where there is low sunshine; unlike USS which does work under those conditions. They replied very generally (likely deliberately) and mentioned future updates improving functionality - this is contrary to what they told you.
I suspect there are sufficient videos about the continued poor performance of the vision system to challenge Tesla if someone was so inclined. Currently I can just about cope with the (cr@p) vision system and ask the wife to hop out and guide if I'm in a very tight spot. If I'm on my own, it all becomes a bit more of a gradual procedure to make sure I don't hit anything. However, my main concern is that the vision system has devalued the car relative to one with USS, although the cr@p performance can be more than inconvenient at times.
If there was some sort of collective action I'd likely jump on it. However, I don't think it's something I would do on my own as whilst irritating, it's not an all-consuming issue for me. Tesla does deserve a poke in the eye over it for sure though. They know it's cr@p but will obfuscate as much as they can to avoid the issue. For now I'll keep my powder dry and the emails and screen grabs of their publications and promises safe.
Tesla just don't give a crap unfortunately, you either put up with it or don't. Its a major reason for me not investing in another new car with Tesla. I'd rather wait until they fully open the SC network up and go elsewhere.
