I would not personally buy a Tesla. It's just not an appealing prospect to support Mr. Musk. I feel he's far too unstable, and there is the question of long term maintenance issues, and what happens to the old batteries.
I did own a Toyota Prius, and it was an interesting ownership experience. The hybrid technology is all about moderation, and the best way to use it seemed to be to overuse the cruise control system. I did average over 40MPG on a trip upstate. My previous vehicle would be sucking fumes of a 16 gallon tank by the time I arrived, and the Prius wasn't even on half. I spent a week driving around, and had enough gas in the tank to make it back, and last the next week too. But the trip involved watching things pass outside the car at a slower speed. I noticed things that I had never seen before, so it was interesting. Toyota's placement of the Prius in the market was rather muted. There was no way to connect a bike rack to the vehicle. The inside was roomy, but a bike barely fit inside, and if luggage was needed to, it was a very tight fit, unless there wasn't a passenger. And if the passenger also had a bike, that was a deal breaker. No roof racks, no roof luggage boxes, no way to help make it fit my life.
I did like the car. It was quiet. The iPod attachment invalidated the satellite radio, which the dealer didn't realize, which was surprising. It could have supported more tech, but it was a pretty good experience, aside from the cartage opportunities.
We need a 'Volkswagen' type program, likely with major government support/ownership to get a truly usable solution for a workable electric vehicle for 'the rest of us'.
I just hope the electric/hybrid vehicle market doesn't look too closely at the e-bike market. One vendor in particular has positioned their entire product line for people that can afford stratospheric cost of ownership. The prices are stunning. I use the price of my most expensive bike I've purchased as a yardstick, and their bikes are double, and not, the cost of that bike. YIKES!!! It's like they are marketing their 'bikes' to those hovering in the rarefied air near the Karman Line.
I'm still waiting for news of an official Apple Car. Maybe that would make them the droid we are looking for, to make electric/hybrid cars more achievable for the average person.
