You're correct in that once you start building for cars your city sprawls out and other modes of transport become impractical.

I don't think the 27% number is particularly useful because it offers no context into the type of trip. No one is suggesting you use bicycles for intercity trips, but for city transport they're perfect. This is reflected in the mode share numbers for cities compared to the national average: Wikipedia has Amsterdam at 40% bike share with 29% public transport and 27% driving. In the context of a city, biking and public transport are the obvious choices to get more people into the same area.

I think you have a chicken and the egg problem in many cities where driving is hugely subsidised and no investment takes place in other transportation methods. For example, in the UK the majority of trips seem to be around 5 miles or less. By bike this is only a 30 minute commute at the extreme end. Once you account for traffic it ends up being only 10-20 minutes slower than driving the same distance.

Compared to the Netherlands cycling only makes up 2% of the national mode share. The difference between the UK and the Netherlands is that we have almost no investment in cycling infrastructure, and what we do get is typically poorly executed.

> Bicycles replace walking, not driving.

Personally I don't believe driving belongs in any city where you also want people to have an enjoyable time walking the streets and socialising. It's a perfectly acceptable way of getting between cities or from remote locations, but within a city there are almost always better options.

That's the thing: in Amsterdam. Who are those people that are responsible for half of all trips and where are they headed with their cars?

Looking at the map I wouldn't drive in this city as well - the distance from the city limits to the centre is less than 5km, so as much as I have from my apartment to the centre of the city I live in, and I generally don't drive into this 5km radius circle around here.

The problem is that the majority of people do end up driving within that ~5km limit in cities that don't invest in public transport and cycling infrastructure. In the UK most cities are around this size, but our modal share for cycling is much lower, despite similar climate conditions. The main difference I see is that we invest heavily in infrastructure suited for cars, but very little in public transport or cycling.

I guess what I'm trying to say is cities typically end up the way they do due to how their residents approach transport planning. You can either continue with a car centric approach that leads to more sprawl and a city center that's less welcoming/interesting to visit, or you can try to make the city friendly towards more efficient modes of transport that encourage people to onto the streets.
