Was stopped at some temporary lights when I noticed that herbal waft comming from somewhere, it was comming from a car a few cars in front of me - windows down and both driver and passenger taking turns on a joint.
As luck would have it the car was going in the same direction as me so I followed it (at a safe distance) for a good few miles, driving was apauling - speeding up, slowing down, and a bit of a weave.
Wish I had my go pro on me if I had I would have sent the footage to the cops.
Might be something that happens in my neck of the woods, but at this time of the year I quite often find myself behind a car with either the passenger or driver or both puffing away on a joint.
I usually take the earliest opportunity to pass it and put a few cars between them and me, some people just dont give a sh*t.
