For some it is about capturing a memorable journey, but for others for evidence in case of an accident - whatever the reason, increasing numbers of people are fitting dashboard cameras in their cars.
In countries like Russia and South Africa, drivers commonly use dashboard cameras as a source of legal self-protection in case of accidents. In Britain we have been slower on the uptake, but now dash cams are increasing as the technology gets more discreet, more high definition and less expensive.
"Sat navs are a great example - originally people had sat navs and it was quite unusual, and now every car has one, every household has probably got half a dozen. I think it's going to go that way - especially when you think about the potential cost-savings of your insurance, of getting someone else to pay for damage to your car, they can pay for themselves."
Police have been using in-car cameras, starting with VHS tape, for decades. But now they potentially have eyes everywhere and dash cam footage is regularly requested in police appeals.
"The police naturally are interested in serious offences captured on camera but not with every minor incident or bump and scrape. Instead a sort of public pillory of online showing and shaming has grown up on social media."
