They are not trolls, it's just war. If I own a vehicle, I don't want cyclists on my road. If I am a cyclist, I don't want vehicles near me.

For me, I would join the pro-cyclist group because I have financial difficulty affording a vehicle. Using the payoff matrix, I want to stand against vehicle owners because it benfits me.
