I think the Zenn is a great step in the right direction. There are many things that, for me, detract from it, but the fact that it exists at all is fantastic. Obviously higher speed would be great, as I don't believe NEV's are as practical in North America as they are in, say, downtown London, but I love the idea of low cost, high quality EV's.
I hope that eventually these vehicles will become available in the country they are manufactured.
