We have both Uber and Lyft that come to our campus. From our experience it is difficult to communicate with them as they are represented individually. If we make changes to a regulation and want to communicate this information to them (as we would with our local taxi companies) it is very difficult. We have some areas on our campus that are strictly enforced as fire routes and restricts all vehicles access, however most times they disregard these areas as many fail to obey signage and there is no way to contact them to correct them.
