Mass transit - that includes PKP, LOT, and metro/tram/bus systems. You guys need to work on improving it, raise your standards a bit, or purchase it all from someone that knows how to manage it better.
There's nothing wrong with most bus/tram systems in Poland. In fact, you're welcome to point out where they can be improved - generally speaking, public transport within municipalities is effective, cheap and reliable in Poland. As for LOT - they're not doing so badly themselves.
Only the PKP Group/Przewozy Regionalne is suffering, and that's all due to uncooperating trade unions who simply don't want to modernise, as well as a Government which is firmly in the pockets of the road lobby.
And hey - at least there *is* a public transport system in Poland.
