It sounds like the parent comment is talking about expanding & improving bike lanes, rather than forcing electric scooters into car lanes (where they are at risk), undersized bike lanes (where they endanger bicyclists), or banning them outright (where you’re now stuck with more demand for car traffic).

Yes, but the comment you are responding too notes, that city streets are not stretchable, so you cannot add full-sized lanes for everyone's new toy.

There's an answer to this, an answer which I see implemented in some places: cutting into the car lanes. Because you don't have to drive through the historical center.

In the cities, where nobody really lives in the historical center, it is doable. (We are not talking about driving through; we are talking about access/servicing; there are very few cities without a ring -- or several rings -- where driving through center is the fastest way from one end to another).

In the cities, where real people live there, it is not. Every part of the city needs servicing, including center. Your plumber won't lug his tools on a scooter; your furniture won't teleport itself into your house either. Every now and then, the residents themselves need to bring in or out their heavier or larger crap, so issuing permits to entry to well-connected companies is not a solution.

Yes, I do live in city center; and yes, we also have people who know nothing about living there, but they go to pub there every Saturday night, so they have strong ideas how it should be. It is not limiting them, after all.

It's never this black and white, also not needed. Usually city centers are closed _for outsiders_, while allowing the residents and local business traffic. This already curbs the traffic a lot and reduces also a lot the need for a second car lane - or such.

Edit: just for clarity: this model is already working (plumbers, movers and locals included).

In 90% of inner city streets you could just block through traffic for cars and reduce traffic to almost zero, without inconveniencing people living there.

You don't need space to have everyone's plumber visit at the same time using an 18-wheeler either. Just converting a few streets into one-way already frees up plenty of space.

So delivery vans and service vans get a permit to drive downtown. Possibly the same for residents (could go either way here, based on housing density and alternative transport options). But personal vehicles of non-residents are banned.

Car lanes are the least efficient use of road space in terms of number of passengers carried, but a lot of the wider roads in Paris only contain car lanes.

We can always reduce the amount of lanes for cars, even from 1 to 0 in very old european cities. Cars were once a novelty too, and all street lanes were engulfed by motorised modes of transportation.

Nobody is suggesting anything of the sort.

In a given area (say a full city block, including all roads and alleys within and bordering that block), you might want...

- Pedestrian lane

- Bike+scooter lane (any transport that's ~20mph and <500lbs loaded). That may or may not include gas scooters (50cc Vespa type).

- Auto lane

- parking lane (could be a mix of bike/car parking)

- possibly a transit lane (bus, light rail, etc)

And you don't need every one of these on every block/street - you can alternate. Or use one-way auto lanes on alternating streets to make room for the other modes of transport.
