Tesla's first production car, the Roadster, you probably already know that it can do up to 240ish miles on a charge -- or an awful lot more in perfectly ideal conditions. Cumulatively, though, they can go much, much further. Tesla has sold around 1,500 of the things since they were introduced in 2008, and the company is able to keep track of just how far each has covered. Together that first batch of cars has just covered its 10 millionth mile, which is probably enough to drive to Pluto or to some other arbitrary feat that usually gets bandied about when these sorts of milestones are achieved. Suffice it to say it's a long way. Tesla says roughly 500,000 gallons of gasoline were saved compared to what would have been burned in conventional supercars, but given the pretzel-like contortions required to climb in and out of these things we're left wondering just how many backs were broken in the process.
