I served on a civil jury where a police officer insisted in his testimony that drivers only have to look left when they enter a one way street from the right because “that’s where the traffic is coming from.” I thought this was a weird statement for him to be allowed to make because a) he was a fact witness and that ain’t a fact and b) he was the officer who responded to the scene where he encountered a bicyclist trapped under a hummer… which was turning into a one way street as the bicyclist approached from the right. (The cyclist won a shit-ton of money, of course).
