I have to drive with weed in the car. Its the most common place I smoke. Either driving around or smoking in a safe spot. I find to never have weed out in the open. I keep it in my center console. You just simply have to give them NO probable cause to look in your car. I haven't been pulled over for anything in 3 years. If I was I would be polite and chances are I'd either get a warning or a ticket and that would be the end of it.
