I really enjoyed riding around these around in Bucharest 3 years ago. Its also something I was thinking about when I went to the future of transport futurists a while back.
It was surprising to see it and other things on sale in El Corte Ingles department store (Spanish department store like Debenhams type), in the same place where you might see laptops or something like that.
I was also surprised about the price to be honest. I always assumed they would be closer to 1000 pounds/euros. There was also a electric skateboard which when I lifted it, was better than what I tried before. I have to say these electric roller skates are insane.
The question still remains about where are you allowed to actually ride these in the UK? I know the UK government set out their strategy for the future of mobility, and a bit more about the last mile transport. But still no clear ruling. I certainly would like to see our streets a bit more like the European cities.
