We’ve known for decades about the benefits of antilock brakes and traction control, but consumers are still relatively unaware of the precise benefits of the latest application of those technologies: stability control. A new study by the Insurance Institute for Highway Safety suggests that up to 10,000 fatal accidents can be prevented every year if the system were on all vehicles, instead of the current 25 percent.

That’s a huge number, given that there are 34,000 car-crash deaths a year. Read this article for a good explanation of how the systems work, and don’t let dealers convince you that stability control isn’t necessary just so you’ll drive out with a car that isn’t equipped with it. According to David Champion, head of auto testing for Consumer Reports, “a big part of the problem is that, since many customers are unaware of the technology or don’t fully understand it, it’s easier for car dealers to tell consumers they don’t need it.”** ****—**Eric Adams
