With cars like the Chevy Volt, Fisker Karma, Tesla Model S etc. on the horizon do you believe they are destined to fail or do they have a fighting chance? Would the cost to maintain them overshadow their benefits? It’s not as though they could be taken to your local mechanic for repairs. I’ve also read that Lithium ion batteries would have to be replaced every 5 years or 100k miles. I would imagine that being quite expensive to do. I’m really hopeful for cars like these…just worried about maintenance.
