Some years ago an American colleague used a piece of software called “Autoroute Europe” to plan a trip from London to Aberystwyth to come and visit us. The route the software offered was.. um… unusual.

I reproduce it in full below, but the point to watch out for is that it involves 3 ferries, and the language of the place names keeps changing! The trip takes me 4 and a half hours of driving plust stops. The software solution gave a route of 52 hours 44 minutes (and about a hundred miles too many).

Tracing the toute on a map has it crossing to France! Driving inland across France before eventually taking a ferry to Ireland, where one can finally take a ferry to Wales!

Now we know why Americans have such a peculiar perception of Europe. :-)

    One Response to “Oddities of Route Planning Software”

    1. [...] This is the route Google offered. Notice that the estimated journey time is 29 days and 22 hours, and rather strangely it routes me via France (Reminicent of this interesting route). However, the real surprise is instruction number 42: "Swim across the Atlantic Ocean 3,462 miles"!!!
