I don't want to diminish Tesla's achievements.
They are well ahead in many respects, and clearly have the edge for now. But it's inevitable that the market will be flooded with roughly equivalent EVs in the next few years.
Ford was dominant in ICE for awhile too. Being a leader affords you additional margin and runway, but very hard to believe it will be lasting.
Look at the Rivian and F-150 for comparable cars. I believe the range may be slightly less, but keep in mind, Tesla still buys most of its batteries from Panasonic. They aren't super proprietary tech that's fully manufacture in-house, though I'm sure they had a hand in the design etc.
Lucid has more range than a Tesla I believe, though is more expensive. EV is in some ways easier than ICE, due to fewer moving parts. But certainly a totally different skill/tech. There are many more new EV startups than there were for ICE at least.
I do agree that self driving can be a strong differentiator if it improves more. In some ways improving it's capabilities makes it more dangerous until it passes the "no need to pay attention" threshold. E.g. the better it is the less humans will pay attention, so there needs to be close to zero critical faults for people to safely rely on it.
From the examples I've seen, the self driving seems very far off from this level when city driving. But not speaking from personal experience. And highway seems like a mostly easy and contained problem, that is unlikely to be a differentiator for long. Most new cars have auto-follow and lanekeeping already which gives you 90% of the benefit in the highway context.
