Not complaining about not having yet another car on the roads here, but your conclusion goes directly against experience of literally every single person living here in Europe for their whole lives that I know. Especially Switzerland, apart from italian-speaking part of Ticino (which is more Italy than Switzerland), people drive well and way above Europe's average. Also Switzerland has 120kmh speed limit, making roads quite a bit safer also due to very frequent stationary radar placements.

But then again we have 0.1% of information to make a good picture of your situation, driving skills and habits, vehicle you moved around and so on. But there is for sure a good reason for such discrepancy, ie driving caravan super slow or similar tiny little detail.

Also you magically skipped few (pretty horrible to drive) countries if you had a road trip that covered Greece.

Have agreed in previous comments that this was subjective (as a family but also as a driver) experience.

Maybe one thing that amplified the effect was the high expectations we had for those highways, and maybe that's what made it more shocking for us.

Again, I consider myself a 'decently skilled' driver, having driven in many countries over the course of the years, and easily adapting to driving styles (US/Italy/France/Iran/UK/India/etc). Some of these styles are indeed chaotic, but they (generally) operate at slower speed, which allow for corrections and precautions. The thing that threw us off is the combination I have mentioned before:

> [...] the speed that those roads allow. The style was quite aggressive, very fast in every lane, loads of overtakes (car constantly zig-zagging), people coming from the back _FAST_ and staying there, people switching lanes immediately after signalling rather than giving some time for people to notice. Overall, that combination made for a very stressful experience which we have agreed (as family) not to repeat in the future.
