Tesla to owners: Plug it in

EV maker Tesla has come under fire for allegations that its vehicles can be "bricked" when their batteries are completely discharged. Such instances require that the cells be replaced to the tune of $40,000, which doesn't sit well with folks who already forked over six figures to buy a Roadster in the first place. Tesla doesn't deny the charge (pardon the pun), but it does offer a common sense suggestion to avoid the problem: simply plug the car in. Tesla implies this danger is only likely for early adopters, and says it's also made strides to idiot-proof later vehicles with advanced warning systems -- Tesla 2.0 Roadsters can phone home to Tesla headquarters with a low juice alert, for example. Tesla documents safe battery charging practices in the owner's documentation, though, so here's an idea: if you're going to spend $109,000 on an electric sports car, maybe it's a good idea to RTFM (read the freaking manual).
