Classic Transport Tycoon allowed you to set a locomotive waiting on a street crossing to run over and destroy trucks and vehicles of the competition. I wonder if there is an equivalent in this game

You were able to send guys with cockroaches, stinky cheese or rats to the competition, then call the health inspector on them. Or send punks there to scare customers. Or you could rough up their staff (and of course make sure to keep gang members close to your pizzerias as well to fight back when they do the same!). The gang members also were able to rob banks or prisons (to free captured mates) if I remember well, but it was a lot of effort to manage this.
