There is this stuff called Liquid Ass, you can buy it on Amazon. It’s meant for pranks but it is the worst smelling thing you have ever smelled. This would be a great thing to keep in car for situations like this. If you cannot go anywhere, might as well get out of your car and act like you support the protest and casually spray it as you walk around. I swear it will at least give you a good laugh, might even get them to move. Lol
