What does the word “incentive” mean to you?

People do drive in London, so they have their reasons (however unreasonable they may look to you). And probably “fun” is down on the list.

Unless you think, Berra-style (https://quoteinvestigator.com/2014/08/29/too-crowded/), that nobody drives in London because it’s too congested. But in that case there would be no need for congestion zone charges to de-incentivize something that nobody was doing anyway.

I get your point but you’re also missing the fact that there will always be a need for private hire vehicles (taxis, Uber, chauffeurs, etc), buses, delivery drivers and other goods vehicles too. Some of the streets I’ve worked in were congested just with those types of traffic and the incentives there are pretty clear: they’re getting paid to driving in central London.

Clearly there are going to be people who fall outside of that group and still choose to drive. As I said in my other post, you’ll always get statistical outliers. But for the vast majority of people who live and/or work in London, we will use public transport, bike, or walk. Some of us might drive into Greater London and pick up the Tube. But very few of us would contemplate driving into central London as part of our daily commute.

Of course not everyone can take their car to the city center every day. It's physically impossible. We agree that the vast majority of people won't, we agree that there are still enough people doing it (very few, but many nevertheless) to create congestion and other problems.

You can defend that charges, restrictions and other disuasory measures are a good solution to diminish the use of private vehicles and its impact. But it doesn't make sense to say that those people have no reason to drive in central London unless they are paid to do so.

Sure, “little” would have been a better term to use but the context of my post was well established. If your only quibble was the use of that solitary word then you’re being pointlessly pedantic.

Note that I was not replying to you in my first comment, I was replying to esotericn's "interpretation" of your comment as people not acting as rational utilitarian beings when they drive in London.
