Do you know Smeed's Law?

The British engineer stated speed of urban traffic is self-regulatingβ€”attempts to increase it are self-defeating.

Avg. speed for #London traffic in 1949: 9 mph
Avg. speed of London traffic 65 years later: 8.98 mph.

Bicycles have *always* been faster.

@straphanger Separate to the benefits of bikes: One of my pet peeves is that because of Smeed's law, one shouldn't pay for expensive infrastructure improvements in hotspots like London (only bike paths and other cheap options...).

Instead one should invest *around* them to mitigate by making surrounding towns more attractive instead by e.g. guaranteeing frequent commuter services for a long time period (decade at least). Much more bang for the buck, and spreading demand over far larger area.
