I think that's a good quote and do believe the true pioneers are those who have asked the question why not? But I think that philosophy goes against the auto manufacturers main focus: immediate bottom line profit. Your right though, govermental regulations could force them to change quicker, but after witnessing the last election I don't think the new powers that be are very interested in regulations protecting the environment or public safety (IMO). As sad as it sounds, I think monetary incentives are the only realistic way of pushing things in that direction.
