I appreciate your arguments but respectfyully disagree.
A GPS guided detour should not be necessary for vital social functions to operate.
I also dislike the small potential for harm to a few individuals when there are better ways to get the point across.

Block construction.
Occupy offices and locations.
March.
Send letters and run awareness campaigns.
Vote.

Do anything you can that makes people see you. Just don’t block the road. To me that is too risky. If everybody would protest like that to achieve their political goals we would live in total anarchy.

Hope my opinions make sense even though you might disagree.
