I busted over 1000 miles on the 4th with the Leaf. It is just so cool to be able to drive all electric with no worry about any thing breaking or just not quite this or that. Hey, home built vehicles have an air of is it good enough or is it something that I can just get in and drive. When you can build one and never have to look back and can just get in and go with no worry then you have done a good job. Until then you are still experimenting with a custom system. Every one does something a bit different and most often the parts are just not quite up to the task. That is not how I want to drive. It is fun building one and building a reliable one but I want to have one that I don't have to worry about at all. The Leaf is just that. No worry. It is comfortable, quiet, and cool. The navigation just works as does every thing else. There is a lot to say about an OEM vehicle that has many many years of research. There is a lot to say about our work too but nothing compares to the OEM. Sorry Jack but the OEM's do have a bit over us in the R&D department.
