In London I have a thousand
options, and every single one of them is clogged at 6 pm. People stay extra hour at work because there is no way for them all to get home.
London has two options - tube or (half each) car or bus. All suck, but tube gets you there fastest (with probably higher level of discomfort as bus does).
Imagine having real bike lanes (and not getting killed) where you'd be able to use e-bikes and e-scooters. Imagine pooling electric car with your neighbour in a Boring tunnel. Even when it's slower you are not a sardine in a sweaty, hearing-damaging tube.
Options dont matter when roads are already clogged. Whether the cars are electric or not wont make a difference.
Bikes/scooter are last mile transport, sure, you can squeeze another 10% capacity out of them or whatever. Maybe another 10% from car pooling. That's it. The only way to get more throughput on the surface is to replace cars with buses. The only way to get more throughput underground is to expand the tube. It does not need to be sweaty or ear damaging, in Prague our metro is really nice, and so is the one in Madrid.
The boring tunnel is basically useless, a hundred of them will move less people than a single tube line.
There is no space in central megacities for cars and the sooner you people realise that, the sooner we can start solving the problem.
