A Tesla roadster dead at the intersection of Sand Hill Road and Alameda in Menlo Park, at approximately 4 p.m. yesterday. Yes, the sexy electric car that's the darling of Valley cleantech investors, on the road that runs through the heart of venture-capitalist country. With so few Teslas in the wild, there can't be that many possibilities on who the unlucky buyer was. Let us know in the comments which rich guy you think was late getting home last night. The big question is, was it a mechanical breakdown, or did the batteries run out of juice? While others may look at this and think Tesla can't manufacture a reliable car, we see this as an opportunity for the fledgling automotive startup: Electric tow trucks.
