I think it's pretty obvious ASO and really all events promote fans approaching the route, except barricades at the finish and on the top of climbs. So for a racer, it's part of the job dealing with it. By the same token, riders often hop on the sidewalk / gutters especially on the pave sections. There clearly can be an edge coming up the outside but it also has its risks. I have more dislike of the crazy moto and vehicle drivers, who are supposed to be licensed.
