Well there's a few problems with that. First of all FWD saves money, complexity, and weight on an ICE car because you avoid a long drive shaft, and you can mount the engine transversely which is more compact. You also get more interior room in the car since there's no hump for the drive shaft. With an electric car you don't save anything with RWD vs FWD, you end up with poorer steering, poorer acceleration, and worse hill climbing, especially if it's snowy or icy. Nor is it cheaper to produce. As a result even electric cars intended for city use like the BMW i3 and Renault have RWD. On the model 3 the rear motor is larger and a permanent magnet motor (which is more efficient) and the front motor is an induction motor. So a FWD would have less power than the RWD, and it would also have less range than the RWD. Not sure Tesla would want to try to sell a car slower (because FWD), slower (because of less HP), and with less range (because of efficiency) without it being cheaper to produce.... just to have a FWD.
