Google maps is an amazing tool. You can literally see the world from your lap(top). It’s killed the route master programs of gone by age and replaced them with a simple “from” and “to” search system.
The problem comes when said system throws a little curve ball into your travel plans (which you won’t even notice until step 48) and suggests the only route from China to Tiwan is to swim it. True, but impractical. I would have suggested a plane… Or alternatively go to Hawaii. It’s sunnier.
