Dash cams may not be as popular in the U.S. as in Russia, where footage from them has produced many popular YouTube videos, but they do have a number of practical benefits for drivers.
Dash cams can give drivers additional "peace of mind," said Johan-Till Broer, Garmin public relations manager, if a crash happens. Having a recording of an incident can help protect against insurance fraud. Some dash cams have impact sensors that save footage for 3 to 5 minutes before and after a collision, said Chris Kooistra, Cobra Electronics' director of marketing. Both companies sell mainstream dash cams.
The device can be an education tool for drivers, too. Parents can review footage with their teen drivers to point out bad habits that need to be fixed and reinforce good ones, said Carinsurance.com Managing Editor Michelle Megna.
