What do you think of the ELF pedal powered electric car that is always out on the W&OD between Vienna and Reston? I don't like seeing it out there because it's too big, blocks visibility, and the guy drives it like a maniac. I like the idea of the vehicle, but just don't think it should be on multi-use trails that specifically prohibit motorized vehicles. It's too bad there's no real home for it, though, because I wouldn't feel comfortable in one on the road, either.

Call me a hypocrite, but I have no problem with electric assist bicycles as long as they stick to normal cycling speeds. I guess my big problem with the ELF is the size.
