I dropped by the The Silicon Valley EAA Rally this past Saturday. It had a mix of homebrew and manufactured cars including the Tesla Roadster. There were some people driving around the parking lot (the “rally” part of the event) but for me the interesting bit was seeing all the cars.
Sadly, the experience didn’t do much to convince me an EV I could use would be coming out any time soon. Plug-in Hybrids still seem promising for the relatively near-future if any car maker is ever convinced to make them.
