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.
