It's still a combination of perfectly decent, nice people, rude people, and people who seem to have something not quite right in the head. The latter category continues to seemingly be overrepresented on buses compared to other forms of transit.
Definitely a much higher percentage of BIPOC, especially immigrants, compared to flying.
(One wonders if this is in part due to the fact that undocumented immigrants can't get the ID they would need to fly.)
