There are many Teslas in our extended family (and as for now, there are a couple of RSRVs on Lucid & Rivian as well). As for Tesla UX/UI, we found it's quite intuitive & fast. As for advanced features, many of us paid for FSD years ago - yet none of us have to experience the "fully autonomous" that Musk promised years ago.
In the last 3 months, two incidents happened with our Teslas that shook the owner to the bone:
- On my sister's Tesla, the car did phantom-break several times while she was driving locally - not engaging in autopilot at all. Then it's all back to normal. She never has any of those driver-assist features turned on. Tesla couldn't figure out why it happened, and since it no longer happens, they won't take the car in for a diagnostic.
- On my cousin's Tesla, one day, the brake just ...STOPPED working. She had no choice but to run into the tree to stop it. Car was totaled.
I would say those who sing "Tesla SW is years ahead & bullet proof......blabla...." may be a bit too optimistic ...
