The track on the island is a grass track, certainly not suitable for cars, ambulances etc. They’d have to use the cycling lane/pedestrian path at least on parts of the way. Doing so at high speed is putting people in danger given, that the width of it all isn’t so large and driving slowly defeats the purpose. Why does everything have to be navigable by emergency vehicles in the minds of some? If every second counts, helicopter is the right choice, if not, taking the established route along existing roads to the highway is the better option, the tram bridge leads to central roads that can’t be navigated fast anyway.
