The technology will have to make sense. Many earlier posts mention similar ideas.
The infrastructure has to be there. Frankly, it is possible that EV technology will not be the technology of transportation in 10 or 20 years. Something else may replace EVs as we know them today.
If EVs were lower in price than current gas vehicles (relative to inflation and such), and the cost of operating the vehicle was convenient, cheap, and clean, then I would consider it for a main vehicle. Currently, the idea that it takes hours to recharge in order to not threaten battery life is just not practical for most people who travel a lot.
