My daughter's car is literally at the local stereo shop right now getting the dashcam hardwired in.

My wife and I have dashcams. Six days after having hers installed, her car was totaled by a distracted box truck driver. We only had back one month from the collision repair after another accident where she wasn't at fault. The other driver had a blowout on the highway, bounced off the center divider, and then took her out. The cops fully attributed the collision to him in the report. A month later, our insurance informed us that he changed his tune, and said my wife hit him.

Dashcams are a must.
