I am surprised that the Tesla marketers and engineers are ignoring, for now, a very significant part of the automobile market, namely those customers that need a 4 wheel drive vehicle or an all wheel drive vehicle for a good part of the year. Subaru, Mercedes, Audi, Volvo, and others offer an all wheel drive vehicle and many more offer a selectable four wheel drive vehicle. I hope, in the future, Tesla decides to market an all wheel electric drive vehicle. It can be, and has been done. One system, on the Japanese experimental vehicle Eliica, has an individual motor on each wheel and power to the motors is controlled by a computer, depending on the traction available at each wheel. The Eliica has eight wheels, is very expensive, and is totally impractical, but it shows that the technology for an all wheel drive electric car does exist. Until Tesla decides to market an all wheel drive vehicle, I will probably stay with my all wheel drive and 4 wheel drive vehicles.
