If sidewalks could be wider it wouldn't be as much of a concern. Narrow sidewalks are to accommodate car parking more often than not. I would rather see less of that in a city centre.
That you know these bikes and scooters blocking pavements is a social ill but you do not care because it is convenient for a fraction of a percent of commuters
Ah I see, thank you. I think they are a blight as well, but less of a blight than car dominance in city centres. If you can barely fit a pram past a scooter on your footpath, see the bigger picture, your footpath is tool small. You have given all your space to non-mixed road traffic or parking.
I've worked in London for near on 20 years. The people using these are not using them as an alternative to a car. If you look about in Z1 the congestion comes from poor road management and an uptick in commercial traffic.
But sure, as a plumber to come to your house on his bike. See how that goes.
The footpaths have been rougly the same around where i live for 4/500 years.
Had a motorcycle accident. Completely pulverized. ICU for a week. Got out and was driven everywhere for a while, but when I walked these were not a substantial burden.
