HGV Dash Camera - Near accident/close calls roundabouts

Nothing too exciting here but it's a good demonstration of why I use a dash cam at work. Here we have 3 different situations where I nearly had a collision with another vehicle due to a mess up on their part. 1. Henley-on-Thames: A Polish car driver cuts in front of me while I'm almost entirely on the roundabout turning right. Pausing the footage when he passes, you can see neither him or his passenger seem to be paying any attention or are bothered by the sight of an HGV coming straight for them. 2. A303 near Stonehenge: I've used this roundabout many times now and some drivers still seem confused about what lanes go where even though it is clearly marked, I've been cut up here more than once and here is one example. 3. A3095 near Bracknell: Just a couple of minutes away from getting back to base and this Astra cuts across into my lane. Nothing too exciting but I get the impression this camera is going to prove very helpful one day unfortunately! The camera I'm using is a Nextbase 402G Professional. Cheers, I hope you enjoyed.
