And I can make an argument, that is at least better than ridiculous, that Tesla has a >10 year lead that is still expanding today on a day for day basis, as the rest of the industry is still chasing after Tesla 2007 technology in the form of the Roadster.I mean - there's the Bolt which makes a decent run at achieving Tesla 2007 technology at a much lower performance point.BMW, Porsche, Audi (everybody else) - they've been promising Roadster competition for years, and they're promising it for a few more years from now. They're promising that when it arrives, it'll actually be competitive with Tesla 2012 / Model S technology, and if it is, then they'll leapfrog over 5 years of Tesla technology and find themselves a mere 7-10 years behind.IF it's as good as Tesla 2012 technology.I do expect fast followers to be able to close big chunks of the 10+ year demonstrated gap in production technology at much faster than 1 year per year, but that's a big gap to close. And using buyable technology today, the gap is still growing - we don't yet have a marker to measure against in order to discern the rate as which the gap is closing.Tesla has a BIG moat
