The drivers in my country emigrated to Switzerland.
I jest, but it's true that my city of 650k souls is in a dire need of around 100 bus/tram drivers and that many emigrated to rich countries which provide an overall better standard of work/living.
Personally for minor errands I cycle because I can't rely on public transport and neither can anyone else, so there's traffic congestion everywhere. I'm not happy with this, but I don't really have other options.
