As readers of this blog will be aware, I use our bakfiets to avoid airport parking costs. I have also fantasised about making some sort of ride-on suitcase so that I could avoid the inconvenience at the other end. The best I had previously seen was the Samsonite scooter cabin bag which I was introduced to by seeing a Lufthansa pilot in Frankfurt airport scoot his merry way -- tie flapping in his self-generated breeze -- in the seemingly endless underground passage between the terminals. But then today, I discovered that someone in China has create that I had only thought about: the ride-on suitcase. Top speed 20km/h. Range 60km.
Here is the BBC piece about it: http://www.bbc.com/news/world-asia-27749176
