The period between 8.45 and 9am seems to be the watershed. Before 8.45, just a few: after 9, shoals. All the way through to at least 9.30, maybe even a bit later.
Tubes and buses, meanwhile, are rammed much earlier. Buses coming down Camden Road are likely to be too full to stop from about 8.15, and the City branch of the Northern Line is hellish from 8..
I can’t explain what’s happening with the cyclists. Do they have different kinds of jobs? Are they different kinds of people? Am I in fact wrong, and there’s some less-than-apparent reason why the evidence is misleading?
Don’t hold back if you have a theory to peddle.
