Doesn't change the fact that you're increasingly hard-pressed to find anyone willing to do it.
Same goes for any type of public transport. The problem is exacerbated in regions of the world which can't rely on immigrants, like mine. I live in a city of 650k inhabitants. The local public transport authority says that they would need an additional 100 drivers to cover all the routes. No takers for these roles and it has been like that for two years at least, despite incentives.
It's crazy because inadequate public transport causes people to choose cars instead, which in turn produce traffic that further hampers mass transit.
Railways have been winding down for decades now and it got to a point where flying between cities in more accessible, punctual and cheap.
Cars and planes are cost-efficient if you *don't* take into account their environmental and human cost.
Otherwise bikes and trains are crazy cheap.
