There are many politically correct reasons to drive an electric vehicle. And then there is the one offered by Michael T. Weiss, star of NBC’s The Pretender: “It’s a great date magnet,” Weiss, 37, says of his Toyota RAV4 EV, not publicly available. “There’s something about it that’s diggable.” Others who dig: Danny DeVito, Woody Harrelson and Leslie Nielsen, electric-car owners all. But the plugged-in wave is still embryonic. In California, officials hoped to see 20,000 EVs sold in 1998. So far, only 2,465 are registered.
