Add fake Trippees to the Grant Croo Pickup

[rlmv]

From Dorothy:

"We had a quick question about the fake trip of the Grant Croo Pick-up. Would it be possible to have it automatically count as 3 "trippees" so that it shows up on the internal bus schedule's passenger count?:

I am not sure what the best way to tackle this is. Possibly by allowing Croo members to be directly assigned to a bus?
