To be fair, I think he always made clear that his promise only applied to
TfL fares,

If you can find a quote from him *before* the election, distancing
himself from "no ifs and buts" into "well, actually... on the trains
it's just daily tube fares, not even seasons, let alone suburban rail
services" a lot of people would be interested.

And at the time it would have lost a lot of votes, especially south of
the river.
...
Of course, and that's why he didn't do something so idiotic. He's a
lawyer-turned-politician, and used carefully chosen, precisely correct
terms that people were free to interpret as more generous than they were.
But he told no lies, even if some people mistakenly thought the pledge was
wider than it really was. He was under no obligation to correct their
mistake.

Please explain to me how "Londoners won’t pay a penny more for their
travel in 2020 than they do today" were carefully chosen, precisely
correct terms that have the meaning you ascribe to them.

Perhaps he found it too difficult to implement a fares structure where
Londoners had their fares pegged and country bumpkins got fleeced?
