But you are my prime example!
You bought a Tesla because you wanted it. You didn't have to. Apparently an automaker built a car you liked, and you rewarded their efforts.
I firmly believe as more people are exposed to electromotive drivetrains in cars they will switch over. Cost, range, and remote refueling are the downside right now. Those are going to diminish with time.
But right now, few people have even been in an electric car, much less lived with one. Things change. There was a time when nobody believed the 1960's horsepower wars would ever be eclipsed either. Oddly enough, if cheap Li battery technology was around in 1975, the death of the ICE as a passenger car engine would have been quick. Cars ran like crap back then and had poor reliability.
