Other manufacturers do have to account for legacy systems, you don't need to be in the industry to understand the relationships manufacturers have with companies like Bosch and know they're not in full control of their destiny.
But their advantage is not a "let's ignore dumpster fire financials quarter of quarter to earn them a multi billion dollar market cap" big.
Tesla is not worth 42B dollars because manufacturers can't figure out OTA updates, and the fact other manufacturers don't have OTA updates should be a rounding error when you list advantages that warrant that market cap. It doesn't take any insider knowledge to know that, just common sense, and for far too long people have been ignoring that in preference for TSLA hype.
I got out last year during the 420 nonsense so honestly I don't know why I'm even bothering with all this, the fact anyone needs more than that to see TSLA is not worth your time is interesting. Anything from that point onward was just icing on the bear cake for me.
Plus lack of legacy self competition, no one else wants to cannibalise their other sales, and no one else has really invested in batteries. Most other car companies can't make enough EV cars to fulfill demand. They're all out of stock until next year because they make so few of them.
We've seen regressions in AP behavior.
Situations where a route that was safe yesterday will send your Tesla into a concrete barrier if you don't catch it
Simply. 100%. Unacceptable.
Honestly, the more I think about it, the more I do not want to be on the road with these people. I did not sign away my life to be someone's SDC test environment after all.
In fact, Tesla's legacy systems are actually a disadvantage perspective, since they have to account for a much larger range of hardware configurations than do legacy automakers.
