I live in a condo and park next to my neighbour in the lot. On multiple occasions as I've gotten out of my car, I've noticed an open can of beer or cider in the the front cupholder of his vehicle. Open containers of alcohol anywhere in a vehicle is illegal where we live (Ontario), as I understand it. I can't prove that he's drinking and driving, or even drives with it as an open container (he's also a smoker, maybe he uses an empty one as an ashtray?).
We're casual acquaintances on good terms with each other, and I'll chat with him for a while if I'm outside while he's having a smoke (which isn't that often). Is this something I should try confronting him about? I feel like if he is doing something as socially unacceptable as drinking while driving, he's not going to care what I have to say (plus, I could come off as nosey for looking in his car. It's not something I've been doing on purpose). At the same time, I feel like I need to do something since he's potentially putting other's lives at risk. Is this even any of my business?
What can I do? Should I do anything?
