Yes there is: lots of gaps and the sidewalk is also available. The outer vehicles can move to the sidewalk and make way for the inner vehicles. There was plenty of space to shuffle vehicles around. Plenty!

You think there is no traffic congestions on German streets?

Besides, in Germany we form a gap in advance before we even hear an ambulance. An ambulacen can usually rush through a traffic jam at speeds of like 50kmh or more.

It’s beyond me why this isn’t a thing everywhere.
