Dash Cams - Who has one?

[ally406]

Doing 20,000 miles a year on rural roads full of nutters persuaded me to spend an Amazon voucher on one. I've only had it a couple weeks, and I've already filmed a guy trying to get into my car at a junction. Thankfully I had the doors locked, and I handed 1080p footage of said low life into the police. However they weren't interested in the slightest in an attempted car jacking/robbery/ra*e, so as it turns out they're completely pointless.
