I don't know how you stop them pinching a dash cam.. something to slow them down 1 minute would be enough, even gluing the cables in so it doesn't rip out first go maybe. You can certainly get them much cheaper I was quoting what I heard someone here paid for deluxe front & rear cams fully installed.
www.facebook.com/DashCamOwnersAustralia/I got interested in that FB group when I came round the corner on the sunshine motorway just as it goes from 1 to 2 lanes & 100kmh. Put the foot down to pass tow truck doing 70-80 in the left lane - doing 30kph faster than him and just draw level and as my view opens up I see a car was coming at me driving wrong way down divided motorway. Hit the anchors and horn. Distance between us closes real fast and I realise we're not going to stop in time. Hit anchors even harder and swerve right into emergency lane - can't go left as tow truck's there - not big enough for a whole car but it's something. Unfortunately other car swerves same way at same time we we stay lined up. Stop with 1m between bumpers. Woman in 60s, well dressed, in new Lexus, done at least 3kms the wrong way. Looking blankly at me scream at her. I had the middle back seat folded down to accomodate a fishing rod - ended up with other stuff from the boot on the dashboard against the windscreen, that's how hard I'd braked. Small S shaped skid on road to this day - but ABS/EBD on VE commodore saved me that day - and my then 2yo in the back. Anyway we all pulled over safely on the left - towie came to talk to me - and she picked a gap and gunned it, disappeared. I considered chasing but thought of my boy and let her go. Towie uploaded footage to the site above - but it was very undramatic thanks to the perspective and you can't quite see me beside him at all. If I was 2m further forward it would have been a much more dramatic vid.
Anyway... foiling going nowhere fast - only been kiting twice in 4 months due to small people in house. Hoping to go more often this year with more work / kindy flexibility.
