I've never actually heard of a bollard. Like what are they? Honestly? Does a city really need to close one particular road so much that they just decided "Hey forget having someone come and put traffic cones out here. Let's just put electronic posts in the ground that can destroy cars if someone hits them!" Regardless of this, the world of Watch Dogs 2 is full of them. Being the ever opportune soul he is, Matt uses these weird unneccesary devices to his own sick twisted enjoyement. Hopefully it's for yours as well.
