I would always have to factor in recharging it.
But apart from that I think it's good if
1) They would cost the same
2) If they were reliable. I saw a test of the Tesla and it just kept on breaking down
60 or 85KWH batteries. Yikes! That's huge. The Chevy Volt has a 16KWH battery.
That will take some time to fully charge.
On 110V a charger is normally limited to a max of 1200 watts. With 1000W being the norm. That's 85 hours for a full charge. Wow!
A 220V charger is normally limited to 4500W. That's still 18 hours for a full charge.
Looks like this car will require a dedicated "fast" charger to achieve some level of practicality. That won't come cheap. My home, for example, won't support such a charger.
Only problem with electric cars is a lack of recharging facilities. And the fact that the energy is generally from burning coal or natural gas, and there are efficiency losses in the grid system, and the fact that the batteries will need replaced ($$$), and lack of range, and hard-to-impossible to get repaired anywhere but the dealer. Otherwise I LOVE them!!!
If we all bought one and came home to our (completely re-wired) house and plugged it in the entire electrical grid would then collapse!
We just don't have the infra structure.
Tesla is another Government Motors with huge federal subsidies.
Hmm, nice for the rich early adopters. Like every new transportation device, it'll need time to get fleshed out and the kinks worked out.
Maybe the woefully inadequate power grid will get some much-needed TLC as the electric utilities realize there's a mint to be made recharging electric cars. It'd be even better charging those cars with energy from renewable sources, but that's a pipe dream at the moment.
