Tesla Libel Suit Over BBCs Top Gear Dismissed in U.K.
The crazy thing is that Clarkson has always said he loves the car. He pointed to beautiful styling, great handling, plenty of power (on a full charge) but it had the drawback of being battery powered and ran it out of juice on the track by driving it like a sports car.
A year or so later James May came to the USA and rented one (because Tesla wouldn't let them test one again). He liked it, pointed out the new features but also pointed out how quickly the battery was dying in the Florida heat. Brian Johnson of AC/DC drove it on the show as well. He said it was a nice car but no thanks.
Jay Leno owns one and he calls it a rich man's toy.
