Erm aren't you forgetting something?
London just quadrupled its bicycle network. That seems like a massive improvement to me. When I lived there, biking was...let's be kind and say "less than ideal". Last time I visited I was amazed by the improvement, with protected two-way bike lanes right on the Thames and much more.

Poster was presenting cars and public transport as the only two options, and complaining that one has been made worse without improving the other.
That completely misses the fact that there is in fact a third option that has been greatly improved, even if poster doesn’t like it.
Hence “Aren’t you forgetting something” rather than “you’re wrong”
A 15 minute walk is 2 minutes by car, five by bike.
Only when the distances are greater than short-walk distance. Cars take up (huge amounts of) space at their destination by parking. You can only push two destinations so close together before their parking lots merge.
For example, you might need to spend some time getting to/from the car or wending your way through a parking structure. You may need to drive a more circuitous route due to one-way streets—-and certainly can’t cut through a park or building. You don’t need fuel/charging or maintenance every trip but it amortizes out to a small delay. And there’s traffic!
Anecdotally, a 15 minute walk (~1 mile) is probably about the break-even point. My spouse and I both went that far yesterday, one in a car and one walking, and yet we both got home at almost exactly the same time.
So it’s a moot point when only one decision pathway can actually be budged by more then a few inches.
They put in some heavy traffic restrictions in my local city of Oxford by closing off residential roads, forcing all traffic down "arterial" roads instead and putting parking restrictions all over the place. A year later, there are no fewer cars on the road or increased public transport usage; some local studies by the university confirmed that. People just spend more time stuck in traffic travelling longer distances.
It's like having a person with an injured leg and a missing one. Instead of giving the person a prosthesis to remove the load, they've just lopped the other off altogether, leaving them to crawl from place to place instead of hobble.
