It’s generally a rite of passage that people get a driver’s license as soon as they turn 18. Most young adults love that as it gives them the freedom to go anywhere they want. But, some may wait longer due to various reasons, and thanks to extensive public transportation systems and the rise of rideshare services, many people don’t drive as much. Some don’t even have a car.
Because dash cams are designed to be installed in a car, if you don’t even have a car or a driver’s license, then you don’t really need a dash cam. It also means you don't own a truck, van, motorcycle, ATV, tractor, boat, etc., because there are dash cams for all these, too.
Of course, unless you are feeling extra generous and want to gift one to your rideshare driver. Or perhaps you might want one for your own protection. A dash cam does protect the car, the driver, and the passenger, just like how the cameras on-board a bus protect the driver and its passengers.
