I would hesitate to comment on a specific company's product. I don't think that's a good role for me personally.
However, I would say that, as I stated in my remarks, the balance between vehicle safety and environmental performance is one I think everyone should embrace; it's not something people should retreat from. The real goal is to have the safest possible transportation system that is also as green as possible, if you like, or with the lowest energy intensity. My suspicion is that the difficulty with some of the very small urban vehicles is a balance between safety and energy efficiency. Again, as an engineer, I can't retreat from that.
