I'm beginning to wonder about the cumulative exposure to this kind of thing and, like, radar from street radar speed limit detectors.
I approached one the other day (no other traffic and I was below the limit) and it started flickering at me, picking me up from 2-250 yards away.
Got me to thinkin'.
Yeah, it's below the danger threshold for one exposure, but between that and radar-operated doors...
Jes' wonderin'.
I'm sure all the authoratays will tell you it's all harmless, but...
...it's still cumulative.
