Glad everyone was ok. The speed may not have been as fast as it appears, as Dan said cars are designed to crumple and as James said the Audi was clipped and spun so would carry more speed than if it had braked.
To give you an idea, skidding to a natural halt from 30mph will leave about 14 meters of locked tyre marks assuming the road surface is in average condition. You can work out the speed from the length of tyre marks as the square root of two times the coefficient of friction (usually around 0.7 for car tyres on normal road) times acceleration due to gravity (9.8) times the length of tyre marks.
However, the marks in that picture are 'yaw marks' not locked tyre marks as the car is sliding sidewards. You may be able to see striations in thr mark where the tyre 'squashes' the springs back as it is forced side on across the road surface.
You can calculate a speed from these marks but it is dependand on them not being more than so many meters apart.
I attend countless accidents where people have flashed to let people go and they have taken it as red the way is clear. We are told on our driving courses never to flash people to let them out. If you want to let someone out then just stop and let them decide to go, never wave or flash etc.
If no one complained of injury then the police don't need to record it however I personally would have reported the Polo for careless driving although it may not get to court due to the fact the other car flashed but that would be for someone else to decide.
