Problem I think is still range.
Tesla model S is no doubt a great, albeit very expensive, car, but it's real world range on European motorways, is still pathetic.
At 100 mph, range is is measly 100 miles, my BMW 535d does 500 miles at this speed, even in the UK averaging 110 mph is quite common, when not too busy.
In Germany one regularly sees cars travelling at 140+ mph for long stretches, which would be impossible for a Tesla.
