I used to when I was younger (as in under 10), as back then the mindset was to tell the bus driver your location, even though by then you really didn't need to but I think it came from previously having to pay a conducter who had to keep track of numbers or something. Then you payed him with actual money (shocking, no flimsy plastic pieces of shit called oyster cards) and take the ticket in front of him, a bit of basic interaction was just expected.
Now its all plastic cards that you swipe on a machine (london anyway, outside of london the buses still seem to use the old pay system). Moneys not even a viable thing anymore, it's not excepted. As a result nine times of ten you and the driver barely even LOOK at each other, never-mind talk in any form. Coupled with all the plastic between us I doubt he'd even hear amidst the traffic and stream of people. It's just not the culture anymore.
Taxes, yeah as the interaction still exists, train drivers no as again no interaction, it's not viable.
