This Spring, in Copenhagen, the new trend for fast transport to get around the city are battery-powered scooters. A couple of companies are providing the scooters that are hired through phone apps of course.

There are two obvious problems that have to be sorted out. First, although many scooter riders stick to the bike lanes, many do not, and if the rider tries boarding tricks of popping up onto the pavement and off or weaving in and out of pedestrians then these things get up quite a speed and accidents are inevitable.

The second problem - and already the cause of heated debate in the newspapers - is that the scooters, even when neatly parked, can be left and are left anywhere so can and do block footpaths. They are also just abandoned - as I spotted here last weekend - and this was not some disgruntled pedestrian moving a scooter out of the way - but a pond well away from the footpath.

OK. Call me old and grumpy.
