If the beacons don't identify their carrier, you could very easily troll AI cars by leaving unmanned beacons lying around.

Good point... Well, that seems easy to police: Have one car patrolling for beacons not attached to what appears to be a person or bike. The only consequence of such troll beacons are cars slowing down on that point, that's all.
