> Acting like a gridlocked highway is congestion but a packed subway train isn't is simply an exercise in broadcasting cognitive dissonance.

The difference is when the subway is full you can add another line or bike lanes or footpaths or trams.

Once the 12 lane highway and 10km^2 of parking you need to provide the same capacity as the subway or ten bike lanes is full there's nowhere to go because adding more car infrastructure displaces productive land use. There is no amount of car infrastructure you can have which will meet demand in a major city, it just forces people to spend more time driving and makes the city worse.
