Can you smell weed from a car?

Excuse me, but I was wondering if you could possibly offer some insight on a particular matter. It's a question that's been lingering in my mind for a while now, and I'm curious to know if you might have any experience or knowledge to share. Specifically, I'm wondering if it's actually possible to detect the smell of weed, or marijuana, emanating from a vehicle. I understand that this may depend on a variety of factors, such as the quantity of the substance, the ventilation within the car, and the proximity of the observer. Nonetheless, I'm intrigued to hear your thoughts on the matter. Could you possibly elaborate on the likelihood and potential factors involved in detecting the scent of weed from a passing car?
