Ease of use maybe, although my parents and grandparents would like to argue differently. They are not as quick to work their smartphone, and the ticket machines are being removed everywhere to be replaced by apps that are much cheaper to run. This works fine for the younger generations, but older and less tech-savvy people are getting left behind.
Quality though, no way. Every single time I tried to give ÖPNV a chance in the last 3-4 years I was either different degrees of late or didn't arrive at all without switching to some alternative method of transport on the way. Doesn't even matter if I tried local routes (Frankfurt and Darmstadt) or longer inter-city connections to Munich or Leipzig, it's all completely broken. People in my company routinely book connections several hours earlier than they need to be places to have a chance of arriving in time, and often are still late. Trains are overbooked, connections are late or often cancelled altogether, seat reservarions don't work more often than they do, WiFi on the trains never works... Many, many things have to change for me to reconsider my default of taking the car everywhere, and I don't think they will in any sort of a relevant timeline.
