Before becoming an automotive journalist, Derek was diving into engine bays and wiring car audio systems for competitions since high school. Granted, there were a few extra bits and pieces after reassembling everything but nothing ever fell apart on the road. Today Derek applies his enthusiasm and gearhead knowledge into the latest cars, unraveling today's complex automotive technology, and learning the rich history of classic cars.
Stop/start systems are becoming more widespread in today's new cars, as manufacturers aim to improve fuel economy and lower emissions. On its face, it's a great feature to have. When you roll to a stop, these systems cut the engine out. That way, you save fuel (and stop noxious greenhouse gas emissions) when you aren't moving. But -- and there is a but -- these systems also have a tendency to lurch the car back into life when you take your foot off the brake.
