For what it's worth, a few years ago I discovered the discount bus lines. Their networks and operations are very efficient (like the airlines, they try to pack all their seats), and for some destinations they're more affordable than even a government-subsidized plane ticket.
Additional bonus: they travel to many destinations that are hard to reach by plane or train.
I'm not sure how they are doing in times of Corona. I doubt governments are queuing up to 'save' them like they save airlines.
