Volvo's Shared 'Care Key' Will Keep Your Teens From SpeedingStarting with model year 2021, you'll be able to set your own speed limits.

Volvo is continuing its bet on safety over speed. The company announced today that, beginning with model year 2021, all new cars will come with a "Care Key." Owners will be able to set a speed limit attached to the key, and anyone using it will be capped at that speed. The feature might be especially helpful if you plan on lending your car to new or speed-hungry drivers, and Volvo is hoping insurance companies will offer incentives to those who use Care Key.

Earlier this month, the company announced it wouldcap the speed in all of its new cars at 112 mph, starting with the 2021 model year. Care Key will let owners set their top speeds even lower, if they choose. The company also announced plans to use cameras and sensors inside its cars todetect drunk and distracted driving.

Håkan Samuelsson, Volvo Cars' chief executive, has asked if car makers have a right or an obligation to install technology that changes owners' behavior. Both Care Key and the added cameras and sensors raise the question of how automakers can and should incorporatenew technologies, especially as so many are developed by theself-driving car industry.
