Tesla unveiled the Roadster 20 years ago. That's plenty of time for other companies to catch up. They made a bet that once the battery moat evaporated the millions of miles of driving footage, powering affordable fully autonomous driving, would be their next moat. They failed, not because camera-based FSD is a silly idea (we drive with our eyes after all), but because it's a really hard problem. If they had won that bet, Tesla would justify its valuation. They didn't, and so we're left with the flailing of a doomed company.

If you count remote control cars as well then you have an even weightier point.

But if you're serious about adapting technologies, countries and drivers to electric cars then you'll know that an electric car being made in the 19th century is totally irrelevent. Toyota even bet big on hydrogen rather than electric for a long time; that's how non-obvious it was.

Great, now do steam. Being produced in the past does not mean it will make a comeback, despite steam being quieter, with great torque, and the main ingredient for propulsion (water) being safer than gasoline for normal people to refuel
