I just imagned a pair of runner teams, both with DocWagon contracts, shooting each other to smitherines and both EMT teams just off to the side...
"Hey, should we, you know, go in there and save em?"
"...Kid, in a situation like this, you should just sit back and relax, cause someone up there clearly got one sick sense of humor." 
That could get bad if one team had DocWagon and the other had CrashCart or something... EMTs start shooting at each other as well....
Yeah, that would be a problem.
Be even worse if one team was
sponsered by DocWagon, complete with logos on their armor and stuff, so they could get a discount, and the other team vice-versa (could be common in LA during a run for Horizon). Then both comapnies would HAVE to get them and prove which service was the better service, and thus would try to bog the other service down by any means possible, including heavy weaponry...
...could even make a mission out of it...
