As an American driver, I've actually driven in Canada through snow (during my holiday break two weeks ago). Over there, they use the metric system, but driving actually feels the same in general. With my G27 wheel in handy, driving in the game feels almost like real life, despite the fact that an articulated truck is being driven and with all of the European signs I see, especially when I drove past a sign that says "Fart Kontrol" (In my mind I thought to myself,
Oh Gosh, I need to stop farting! ). But I do drive defensively even though the AI has funky driving dynamics. If they give way to me even though
THEY are on a priority road, I proceed with caution, looking at the other direction for more traffic. I follow the country speed limits given from every border crossing. If I am carrying a heavy/oversized load, I drive at 70 km/h with beacons since the speed limit is indicated on the trailer. Carrying a normal load, I drive at 90 km/h on motorways, multi-lane highways, and single-lane roads unless specified by signs, or if there is a sharp corner ahead in which it is indicated on the SatNav. Overall, I am a defensive driver.
I must also point out that I made myself a mod where AI speeds are matched to the country speed limits for every country. So driving on the single-lane roads are...faster.
