> Isn't Not Just Bikes some US expat/biking maximalist?

According to their videos, they prefer trams within cities; generally take trains between cities; and acknowledge that cars are very useful for places which aren't so well connected (e.g. places that are far apart which aren't on a train line). They think encouraging the use of cars within cities is a bad idea (dangerous, scales poorly, makes those areas less pleasant to be, etc.).

Not what I'd think of as a "biking maximalist".

They do show themselves cycling to places that are nearby. Does that make Youtubers who record videos in their car "driving maximalists"?
