The point I was trying to make is if the rider was not speeding and in the same spot he was when the cop pulled out there still would have been a collision. Mind you he may still be alive but we don't know that.
Most U-turn collisions happen due to someone pulling out in front of someone when it is too late to make any manuvers or slow down.
My brother was hit by a cabbie doing a uturn in a blind corner, brothers speed was no more than 30 kms an hour as he had just made a turn onto that street from a stop. No way to avoid it. Now imagine my brother being on a bike not in his cage. Could have been fatal then, regardless of his speed.
Dicsusion is good to see all points of view. No need to talk to people like they are dumb for not having your ideas or thoughts.
And the point I'm trying to make is that you're assuming the distance involved would not have been sufficient for the rider to stop or evade, if he was travelling at the limit. This is a complete unknown; the assumption cannot be made.
