Yes, my destination is now Charing Cross in Glasgow – slightly out of the way (but arguably my fault). It also appears that I have to swim there. At least I get a stopover in Belgium!
To be fair, Google Maps did provide me with the following warning:
Walking directions are in beta.
Use caution – This route may be missing sidewalks or pedestrian paths.
How true – there aren't many sidewalks or pedestrian paths in the North Sea...
