No - I meant that for the VAST MAJORITY of people there is no point in owning a car if you live in London.
I don't accept the above; carry on reading.
If you want to spend your life making Socratean arguments and pointing out every possible exception, then go ahead.
Usually we talk about the majority use case not tiny exceptions. Yes, there will be a small number of disabled people - who get exempted from things like ULEZ and have blue badges. Then there are builders and plumbers. Not sure why carers need cars unless it's to transport the elderly. London has a 24/7 transport system.
You assert (quite emphatically) that the "vast majority" of Londoners don't need transport, but don't provide any links or stats, or give your assumption. I've been googling. Here's what I found:
1) London's transport network is excellent, and can additionally be supplemented by taxis/ubers/boris bikes/etc where appropriate (at a cost), but it's far from 24x7.
There are ~700 bus routes in London. The night bus covers approx 136 of them.

The night tube is only Fridays and Saturdays, and covers only a fraction of the network.

2) Google says approx 18% of the population are disabled; so potentially there is more than a "small number" who need a car, although this will be part-mitigated by free transportation services such as dial-a-ride provided by TfL.
3) The elderly (that's also ~18% of the population) also get free transportation services, dial-a-ride, TfL and National rail services. However, that doesn't necessarily replace personal transport requirements; I don't know anyone who has given up their car when the received their freedom pass.
4) You acknowledge builders and plumbers needing transport, but not roofers, carpenters, floorers, electricians, architects, glaziers, landscapers, gardeners or any of the other trades. What about Doggy-day care, cleaners, hairdressers, podiatrists, etc? In fact, there are some 4 million self-employed workers who by definition have no fixed job, so might be more likely to need a car.
5) Some carers certainly do transport their charges, although a more common travel requirement is business mileage between houses to provide domicilliary care. There's not enough time in the day to rely on public transport, even if the network was conveniently close enough, to say nothing of equipment that might need to be transported.
6) Other social care and health care roles involve home visits; social workers, district nurses, health visitors, cancer nurses, midwives, and GPs. This requires transport.
7) Driving jobs. Any job that involves driving a provided company vehicle (so bus drivers, taxi drivers, firefighters, police officers, paramedics, etc etc etc) - by definition they are already "drivers", so they probably already have their own car.
Considering all the above, even if there is overlap in the groups, I just can't accept your first line that I quoted.
