So no Ill speak towards your brother as he has the right to ride on a bike lane, but does said car park have a warning strobe and siren to indicate a vehicle is leaving towards the cycle path? They typically go off resonably early to warn cyclists. Its not law i dont think but its an insurance thing for building owners to shed liability. Ive installed heaps in my time, whether it be an inductance loop in the ground or run off the boom gate being actuated.
