Quoting Trent W. Buck (trentbuck@gmail.com):
They can't even get to the German airport, because Article 26 deliberately punishes carriers (i.e. aircraft, ferry, bus operators) who allow refugees to board in the first place.

This forces refugees to use dangerous, illegal, and expensive routes, e.g. €10,000-€12,000 instead of USD$400 for Turkey to Britain.
A couple of weeks ago, my wife and I happened to travel on a bus up part of European Route E60, the portion of that motorwayfrom Bucharest to Vienna. Our guide says this has been in recent years the primary route used by migrants from elsewhere in Asia and Africa up into western Europe. He said that, since this has been happening, border officials at the point of entry into Austria have been doing at least visual checks of all motor vehicles, particularly since a lorry was found to have been sealed with dozens of migrants who had all suffocated to death. Because of the carrier controls you mention, the border officials' scrutiny is said to be primarily focussed on lorries, but they did give our bus a good look, too.
