I guess you chose to ignore the bit where he drifted across the cariageway while playing with his camera. I am against anything that encourages people to drive badly. This seems to encourage people to focus on filming and looking out of bad drivers to film, rathger than on their own poor driving skills.
I can’t imagine why someone should be arseing around with a dashcam, because once set up and put in place, it should function automatically. Because of the miles I drive every day now for my job, I’ve bought one just to have footage in case of there being an accident that needs witness footage, and mine doesn’t need to be touched at all.
It’ll give seven hours recording on one 32Gb card, so I stick it in place when I pick up a car, and let it run.
If, when I renew my car insurance, I get a discount for having a dashcam, then I’ll happily embrace the saving.
