I actually loathe driving in Poland, and wouldn't even consider buying a car here for that reason.
When I drive here I occasionally let other drivers who don't have priority out of their road. About a third of the time I get a thanks (about the same rate of thanks as I get when I give up my seat to an elderly person on a tram or bus).
When I walked out yesterday, I was witness to 4 near-misses:
1. A driver nearly slammed into the back of another at a traffic light queue in Bielany W.
2. A driver came across a junction on the wrong side of the road somehow, perhaps he'd left a nearby shop or house. Bus nearly smashed into him.
3. Car mounted pavement to overtake car in urban area roadworks queue that was starting to pick up speed but obviously not fast enough for him in his big new Land Rover or whatever it was. He drove like a bandit.
4. Car screeched away in Tesco car park only to have to slam its brakes on 10 metres away anyway where queues formed.
Barely a trip passes when I don't see 2 cars nearly collide at a crossroads. Tailgating and speeding and being on phones are almost every other car round here.
