Thought I would share my story with my Tesla purchase in the early days of their FSD promises for those debating the DD/DDP.
I went to the Tesla studio to test drive, build, and purchase my Model S back in in 2017. I was told by the sales rep and it was clearly described on the Tesla website (wish I took a photo - I'm sure it's floating out on the web somewhere) that purchasing FSD would future proof me on their developments and ensure my vehicle will be apart of their vision they are building with FSD by having all the necessary hardware and that they'd upgrade my hardware if needed to achieve it.
5.5 years later they did 1 free upgrade which was my internal computer hardware, but if anyone knows the MCU1 Vs. MCU2 fiasco which is a disaster, Tesla claims the MCU1 can handle FSD which is just BS and they are dragging the timeline on that. MCU1 is archaic. I paid to upgrade to the MCU2 ($2750, had to pay $500 extra just to keep FM/AM radio
) because of how bad MCU1 is and I couldn't deal with it any longer on a daily basis. It was super laggy and non-functional many times requiring 5+ min reboots yet Tesla is claiming this control unit will handle FSD. They are already on MCU3 on the newer Teslas and it's already been said that previous models will not be upgradeable.
Even still, my Tesla does not seem to have the newer full color cameras, and I have no idea what cameras will be used for their new Tesla Vision that is being rolled out.
I really do think once there are more Lucids on the road sending back data to Lucid, they will enable Highway Assist on DD models once they can get more comfortable with the cameras doing this job safely despite Lucid employees saying otherwise. Though a little different, I remember when Teslas were doing an "uncorking" to allow more power out of the Model S built after a specific date/year. I was told my car is not eligible. Couple of months later, my car became eligible for uncorking (AWD models), and a couple months after that, RWD became available. I believe Tesla was taking in data during that time to ensure uncorking for the previous motors can be done safely for longevity.
