I think a lot of people do have the technology, but it’s a big change. It’s like a steam train company changing to diesel. 60% the same, 40% completely different.
Audi is launching the e-tron GT, a direct Model S competitor later this year, and a SUV (I think model X compeitor) any month now. Jaguar also launched the i-Pace to big accolades last year. I think the next 2-3 years, we will see the current auto giants jump in the electric market in a big way.
On the other hand, I read that Mazda thinks gas-powered will be around for another couple of decades (I suspect they are right). I don’t think I’ve even seen a hybrid concept from them yet. When I compare electric cars to similar gas powered cars in the more mass market sector, it’s hard to justify, imho. I don’t think it will get cheaper fast because batteries require a lot of material. There is no clear short cut for that.
