Dash cam
A couple of weeks ago, my dad was involved in a collision with a gravel truck. The truck was doing about 65 mph when it drifted into his lane, struck the left rear corner of his Prius, and spun him counter-clockwise 90 degrees and directly in front of the truck. As the truck's movement was constant, my dad was then pushed down the highway, sideways against the truck's bumper, until they came to a stop. Fortunately, my dad suffered only minor injuries from the shattered window. His car, however, ended up with about $12K in damages. Lacking independent witnesses, the CHP was unable to find one or the other at fault. Because of this incident, we each bought a Blackvue DR500GW-HD dash cam. Unlike GoPro and other digital cameras, these are basically install-and-forget cameras that are there to provide recorded evidence in the event of an accident. They run continuously, recording the newest segment over the oldest. While they are usually installed behind (in front of?) the mirror, I've temporarily installed mine on the Vector Offroad JK e-dock with a RAM mount part and zip ties and am looking for a better solution.
