A lot of Tesla fans have been saying how the incumbents are unable to compete with Tesla in the EV segment, and with all driving going electric this would mean very high Tesla market shares in the future car market. 10 years ago this was the case indeed, Tesla was way ahead. But the issue was that these people haven't updated their views to today, and still keep repeating that belief. Now, incumbents have brought out very strong car models onto the market, at really competitive conditions. The future is electric, yes, but not with high enough market shares for Tesla to to justify its share price (which in fact is so high, even if Tesla had 100% market share, it would still be unjustified but that's another thing). The patent opening also happened 10 years ago.
