Right hand drives in a left hand drive country are too dangerous for overtaking.
Only when on bendy stretches, on a straight run by keeping your distance its quite safe.
I have been driving to Poland through the continent since 1990 with no such problems.
The accident rate in Poland is simply down to the incompetent idiots they let on the roads and nothing to do with which side they drive on.
I absolutely agree with this quote, plus the rest of your post.
This is what the Poles lack. I have waited to pull out onto a main road until some 50 cars have passed with not one giving way. What arrogance !
On traveling a 3 - 5km straight stretch and being tail gated, the Polish motorist decides to overtake me on approaching the last 100metres when a bend is coming up. Regardless of the road signs and double white lines. Do they know the highway code ?
Not to mention,
Driving stupidly fast is perfectly accepted by Polish society and drink driving isn't much frowned on.
Are these people for real ? Speeding and drink driving accepted ?
Try asking that to the families of those victim to such fatalities. Ignorance !
Scenario; Empty road and the Polish motorist overtakes you, cuts in front, reduces his speed in ratio to yours: Was it worth overtaking ? Whats the point ? Was it, just to be the one in front ? What kind of mentality is that ?
They simply have no road usage ethics or courtesy. If I were the Polish transport minister, I would certainly make passing the Polish driving test more stringent. I would also look into driving licenses that may have been fraudulently purchased in the past.
If you have competent drivers, regardless of what the drive side the vehicle has, you have safe motoring.
