yes, they went from boring eco-boxes to something sexy. they let designers and engineers have pretty free reign instead of bean counters, and they executed on the package well. and it is a great product, i don't disagree. but that doesn't make it a "true engineering marvel." your fap to metric is drag racing supercars, but there is enough talent on this board to come together and build an electric car that could do the same. is it an engineering marvel if a few yahoos can get together and do this? i'd say a true engineering marvel is one you can give a handful of yahoos infinity years to do and they could never do it.
as i stated, electric cars are over 100 years old. and you can read in popular mechanics from 1910 about the batteries that are going to bring them to the masses just being around the corner. nothing has changed even though you are a tesla fanboy. ICE is not dead, it's not going to be dead either. hybrids are the future. with some EV for niche cases, like city cars, or toys for rich people. joe 6 pack in the burbs is likely going to have a hybrid though.
You said its been around for 100 years, and is easy to do, but no one else has been able to come even close to the success that Tesla has delivered.
The Model S has been out for how many years now? No other car even close yet! Additionally you're ignoring things like autopilot. Tesla revolutionized a true auto pilot in a car!
The neck snapping speed of Tesla's is something worth mentioning. All these "hyper cars" and "drag cars" come out and still cannot out accelerate a Tesla. Again, if it was so easy, why can't anyone beat them?
