Google can't even find a route (Is it possible? I presume that you
can't walk the tunnel along the "bike" lane now that taxis use it)

ISTR the fact that people could use the free buses was used to justify
the fact that now not all parts of the airport are accessible on foot.

I assume their lawyers are prepared for a DDA challenge from someone
with a proven aversion to buses
