Whatever the hell it is you're talking about with mindshare and flops in peoples minds, I'm pretty sure GM and Nissan have sold a lot more electric cars than Tesla.
You might need desire. What I (and millions of ordinary people) need when it comes to cars is a cost-effective solution, which means resale value, parts, cost, petrol etc. Desire comes last.
Agree - Tesla taps the passion of the die hard enthusiasts. The range and performance of the Model S is comparatively exceptional to that of the Volt and Leaf. Model S is sexy and exciting and I WANT to drive it, I don't simply concede to drive it as a best option.
