Going back to an earlier question—I'm jumping around a bit here—with regard to the battery solution, I'm trying to get a better handle on what you would be asking of us or what your recommendation to us would be. Mr. Allen, you said that charging standards are going to be important in terms of where we go here.
From an electric battery perspective, I'm wondering if there is a way that government can support industry with a more common platform or set of standards that tend to commonize the platform, which reduces cost and helps to create greater efficiency, if you like, without going to the Beta-VHS example that was used earlier.
You mentioned the units at gas stations across the country, but are there enough similarities or enough issues that we can be a help to that?
