General: Polish roads are not in a poor quality. Beside of that, hitchhikers should not mention the quality of roads, they should have other worries. The Polish road network has improved gigantically over the last 1.5 decade. The roads are fully up to doing what is demanded of them. If you say the roads are bad, it means you need better roads. But why do you need them? I do not understand that. Do you feel better with top end roads? Would you like over 10,000 km of fast motorways, as Polands western neighbour has? If so, why? Aren't you a simple hitchhiker. Take care and take your time.
Langauge: An insult to Poles! "are unable to speak". Hm. What to think of that. And still apart from that - I guess that about 1/4th of the Poles speaks English, 1/4th of the Poles speaks German (if just enough to travel - which is your goal - not to insult people be careful with what you say), all speak Polish and half of them speak Russian (if just a bit). Czy ty mowic pan po polsku?
