I kind of mixed up two arguments. My main argument was that there is definitely a need to invest into "yesteryears" public transport systems, because the new services are not affordable for anybody.
and the other argument is that new "high class" bus services take money out of public transportation, which is badly needed there, but as you said, this may not add up to much. (However I could see myself switching from public transport to self driving cars, so they can also be included in this argument)
But both arguments go in the same direction - that public transport is definitely necessary and will remain necessary in the future but is often neglected and in a really bad condition.
