The again on an "open toll road" would you expect a gtr to come flying up the inside of you? The Clio wasn't indicating right so clearly had no idea there was a third car and took the corner as normal.
Having been to the ring a good few times before (not to brag but around 24 times in 11 years) you are so wrong with this and on other posts
This is germanay were they drive on the other side of the road so there was no diving up the inside, it's a two lane, public toll road amd you have to treat it like any other german road so keep to the right unless overtaking.
The GTR was the faster car so was in effect overtaking the other car, the clio the clio driver was doing right by keeping right but, i can only assume did not see the GTR hence the turn in, sorry but it was the clios fault. The police would have attended this incident because it is an accident on a public road and faced with the camera evidence or any witness evidence will point the finger of blame towards the clio driver.
Please dont let the videos you see put you off the place, as a petrolhead you'll love the place, it's just a great place to be for a petrolhead but please please please read the rules and stick to them, they are on big signs in the grunne holle car park were you buy your 'toll' ticket, european law dictates you need insurance to drive in europe, most uk policies give you 90 days of cover to drive in europe and this covers you to drive on public roads in germany, yes its a grey area about not being covered on 'the ring' but as i say, european law says your insurance covers you, if this was an english car involved your insurance would have to pay out or help you claim against the other, what they do after that is a bit of an unknown.
Please don't call it a track day or treat it like a track day, there are separate events for that, it's a public road, there are acctually a couple of speed limits on there and if the law wanted to be funny or you had a mishap on those parts you could be in bigger trouble.
And yes it is bad to start the stopwatch under the bridge to time yourself, i'm not 100% but this also might be illegal but if you did have an incident and the police turned up to find a stopwatch on your dash the length of your stay in Germany might last longer than you wanted
