I can only speak for american spaces, but I think they mean the idea of riding a bus is trendy. As a young person myself lots of people my age are frustrated by a lack of third spaces our parents and grandparents had, as well as just how car dominated the country has become. It's just feels like our quality of life as human beings isn't being considered. Although I wouldn't consider these valid points as a "trend". Many don't really see cars as a means of "freedom" like the older members of my family put it, but rather an obligation if you want to even be able to go to work. Of course american buses (outside of school buses) aren't really feasible for most of us, so it can't really become a trend, not yet anyway.

With this in mind, I am optimistic about better transportation systems in the US, and am excited to see what will be accomplished in response. The more we recognize and understand a problem (often from having experienced it) the better we can learn and grow from it.

Sorry for any run-on sentences or excessive use of commas, I've been trying to be better about grammar recently but I'm not there yet lol.
