Hey! it depends of the zone where you're i have spotted cars on dangerous zones and safes i never had a trouble with that. just in some cases people looking rare at me but that's because people dont know that its for this hobby they can think bad, personally i spot cars on empty streets when nobody is looking around (this when i am walking) and with my personal phone. Just being discreet & photograph fast more easy and recommendable spot inside a car or from a high alture
