Nope, in London those with the high end strollers bundle them into their massive 4x4 urban tanks - another way to show selfishness and self entitlement. Those who use the bus have disposable kinds that periodically buckle under the kid and overstuffed shopping bags. Having been a wheelchair user in London who has had to endure literally hours of waiting (and boy, do you get cold in a wheelchair even on a warm day as you don't move) because bus after bus could not accommodate me - spaces filled with unfolded buggies, I can attest to the self entitlement. Have made absolutely sure never to encroach on a wheelchair user in any way.

As to the topic, what I hate about travelling in Tokyo are the self servers who ignore those around them when using the guard gates at the entrance to stations and at the elevators. They may be in the minority but given the crowds and number of people involved even a tiny percentage means that they have a strong presence. Being pushed in front of time and time again as a wheelchair user got wearisome, as someone who has visited more recently with a small but wide wheeled buggy I've got to witness this inconsideration again. It actually seems to have got worse in the last few years. Never saw a buggy user who didn't offer a place on an elevator to a wheelchair user first, saw plenty of jerks with no clear need for an elevator charge on and hit the floor button rather than the <|> open door button whilst others boarded. I suspect they wilfully fail to notice those who have needs greater than they own and are to all intents actually blind to them. May get worse once spectacle computers become more common place.
I guess, with the majority of people being courteous and delightful those who aren't feel they have an open field to exercise in.
