Nice, I like that.
I guess I’d have to remember to turn it off going through toll plazas and toll lanes.
I have the personal one. I wandered around all of NYC with it on.
The only time someone noticed is I walked into Luis Vuitton with my wife (who was spending serious cash there on luggage) and the security came out and was (politely) looking me over, like they were afraid I was a ghost or an alien or something.
