VehicleSpotter
It happens to me a couple of times in the past, so don't worry about it, Unfortunately, some people think taking a photo of a car mean owner did a bad thing on road like pull out in front of you. Here is some tip for you or any spotter is keep calm and tried to explain why you took the photo and they still cause a problem, just walk a away from then.
I was still worried about the police car, though. "

id he call the police? Am I going to get a dressing-down?"
I've looked up the NZ Police guidelines on taking photos in public; it is lawful to photograph people in public without their consent, except where they can expect privacy like public toilets. So I reason, "If these are the laws on taking photos of
people, I imagine it will be more lenient for cars."
I was given the advice that some people like what I'm doing and some people don't like it. That guy just didn't like it.
