I'd suggest it's because people don't do basic research before handing over a wad of cash to sellers.
Sorry do not not to agree with you, many of my neibours have Teslas and I asked over 10 individuals for their views. I had an initial test drive early September, followed by an extended test drive a week later after having looked at on line tutorials and familiarised myself with the controls. I tried nearly all the features in the 90 minute period, I could not try summons or park as it required the app and I was only given the card, but summons was demonstrated on another vehicle by the sales team. I was especially impressed with the USS as it actually showed distance in inches. I question the sale staff who I thought were very honest and did point out that FSD
does require driver to be in control but if purchased software and any hardware (if required) would be added with constant improvements to autonomous future driving. At no time was there any pressure to sell and I believe true explanations was given.
A few weeks before taking delivery i was sent the vision disclaimer, but Tesla attached statement stated restrictions "for a short period of time" Having signed the disclaimer and having thought about it the following day I contacted Tesla Customer Services to cancel the vehicle. Over a number of telephone calls I was advised that the USS had been removed and that Vision far superior system which would replace the sensors and restored by over the air software. This would only be very short period of inconvenience whilst the software was released. Having some concerns I followed up my telephone conversation in writing and I was assured that Park, Park assist, Summons and Special summons would be available in the new year. Furthermore if I did cancel I would loose the vehicle and go to the back of the que.
Having both verbal and written assurances I proceeded with taking delivery of the Tesla Y.
Clearly I was not aware and maybe customer services persons were kept in the dark, but Tesla were fully aware that they were deceiving customers to get money and to avoid cancelation which would affect end of year sales statistics. I therefore believe that Tesla with full knowledge have acted dishonestly and they have a case to answer or deliver the goods which have been paid for in full.
I said in previous threads, every discontented customer is a negative public PR advert which gets passed on from one person to person, I am sure that this issue has caused or will cause Tesla problems, especially with Mercedes having acquired level three in some areas and Tesla facing competition for other EV vehicles, who inclinedly deliver the vehicle to specifications.
I would be happy to learn from your experience of what more I could have done, so that I can pass the information onto prospective customers.
