I think this is unquestionably a problem in modern society. Too many interactions are purely transactional. People are isolated and lonely. Many people are only out for themselves. Community has definitely broken down
I don't know how to fix this and I'm definitely part of the problem, but I think it is a very big problem
If you know your neighbors, you are less likely to run them down on your e-bike.
And if you know your neighbor and maybe even rely on them somehow, it makes it much easier to accept certain behavior or opinions for example. It's much too easy to dismiss other people because they don't look like us or think like us, there is no downside because everyone only needs themselves.
It's sad but my hope is that the climate breakdown, wealth inequality for example will eventually lead to a "rebuilding" of a more localized society where we depend and help each other. Maybe hard times will come and give us a bit of a shake as a species.
