I was looking forward as I entered the road and moving slowly as I just started from a stop sign. Would have never hit a pedestrian. It's a 50mph zone, the passing cop came up pretty sudden. He may have even started the pass just before I started turning.
The point is, you don't know whether or not this is true because you didn't first look in the direction you
would be going. Safe, responsible driving demands that you do this 100% of the time.
I'm happy for you and every human involved that there was no crash and no one was hurt, but I sincerely hope you are able to absorb this crucially important lesson.
I'd like to add that, if you had looked as carefully and fully as you should have, and the bolded was true, you would have been able to notice by his relative rate of speed and closure rate on the vehicle in front of him that the cop was about to pass.
Anyone who thinks that, gosh, this is just too difficult to do, shouldn't be driving.
Edit: I'd like to add that I'm not trying to pick on you, OP. My apologies is the stridency with which I make this case comes across too personally, but defensive driving is important for everyone because it saves lives.
