Helmet cams have become increasingly popular among motorcyclists, both for fun as as a way to document possible incidents and accidents.
Roundabouts are generally a good idea when it comes to easing traffic flow, as they eliminate traffic lights by keeping cars moving more often. They are not, however, great if you're the driver of a semi with a particularly oversize load. Depending on the length of the trailer, in fact, a roundabout may be a wildly difficult obstacle, requiring its own degree of special equipment.
In the US, the four-way-stop intersection is king, with little competition from roundabouts. In Europe, things are reversed, and the roundabout is much more common than four-way-stop intersections.
