10 Most Useless Car Technologies

In theory, the ability to manually shift an automatic with nice, prominent steering-wheel paddles makes some sense. Many of us don't want the inconvenience of a manual transmission during the daily grind, but who doesn't want to manually change gears once in a while? On some cars, like the AMG Mercedes with the seven-speed auto box, the paddles work fairly well. But we've often found that that the computer-controlled transmissions are far too reluctant to respond to driver inputs. As just one example, we've tried on multiple occasions to actuate the paddle shifters in the five-speed automatic in Acura's nimble new TSX about eight times before one corresponding upshift occurs. Unless the paddle shifters are calibrated properly, they're just another pointless feature.
