True. That's because of the way they get spawned. They get spawned with the idea of racing against 1 opponent. When the oppnent is in front, the police gets spawned in front of the opponent, so the police will see the leader first and start chasing the leader, not the player by default.
But with 29 opponents, they still get spawned i front of the leader. That's why you only started to see them when you were at the front.
I'm about to change that.
