While looking up driving directions on Google Maps from Barcelona, Spain to Madrid, Spain, I clicked the option for “walking” directions out of curiosity’s sake.  This is the quickest route they gave me for walking.  I don’t think that’s the most efficient way to go.  First of all, I can’t walk on water.  Second, why not go straight over land.  That appears to be a shorter route.  What makes this hilarious is the statement in yellow:  “Walking directions are in beta.  Use caution - This route may be missing sidewalks or pedestrian paths.”  Missing is, “We may send you walking over water.”
