I've googled to hell this subject and have not found what I am looking for. i know we have some very intelligent people on HUKD so can anyone hep me with this.
There is a reason police do not set up speed cameras on bends of a road. I know of a motorist who in court argued that a police car travelling some distance behind him on a straight road could not accurately judge his speed as he was on a bend in the road and that due to some 'effect' he would appear to be travelling faster. He won his case.
He did mention some 'effect' that in science directly supported his argument, I just need to know what that is.
I have some idiot who pulled out on a roundabout on me, he says he entered the roundabout first. This means while he travelled 5ft to the impact area I travelled 75ft (from behind the white line) to the impact area in the same amount of time. That's 15 times faster than he was going. No I do not drive an F1 car.
As well as the mind boggling speed I would have had to be travelling at that point, I want to use the scientific fact about cars and perceived speed on a bend. (i.e. on the rotator of the roundabout)
