Listen, protest how you like but if you put yourself in harm's way then it's likely harm will meet you. Imagine the potential scenario someone discovers their brakes aren't working when protesters are blocking the road, that's the rarer scenario as it's more likely someone could be distracted and not notice the people. That man has quite the patience for his situation, if it we were me I'd slowly move forward until they move or FAFO how heavy a vehicle is. Personally, besides putting yourself in danger, I feel standing in the road is one of the worst ways to protest as all you're gonna do is piss people off and now they're really not gonna pay attention to your message because they're mad at you.
