Tesla, to the extent they sell a large number of cars, will be single-handedly responsible for congestion and traffic jams with drivers consistently driving 5-10MPH below the speed limit. For some reason Musk has made that “OK”.
While Tesla drivers won’t be breaking speed limit laws they also will not be breaking any laws of Thermodynamics either.
The lowliest of sub-subcompacts will always outperform the Tesla in every meaningful way that one measures an automobiles performance.
Musk’s genius is in packaging (It looks cool so it must go fast, and indeed “can” as long as you recharge it frequently). In the end these cars will be pricey annoyances to the folks that drive them with any frequency, and also to the long line of cars behind them just trying to get past them and down the road to where they are going.
There is a pretty good speed penalty. The way I read the charts, a 30 minute 200 mile supercharger fill up may only get 100 miles or so driving 70 mph into a 20 mph wind.
