I'm going to throw a wrench into all of this.
You said this occurred in the parking lot of a hi-rise apartment building. Who owns the apartment building or grounds they are located on? Is this public housing by any chance or owned by a government agency? I ask this because some states (California for one) have obscure laws stating that when public traffic is allowed on paths, roads, parking lots or grounds that are publicly owned, traffic laws are just as enforceable there as they are on the highway.
If you were on on publicly owned land, you may be in a similar situation.
