We did a big road trip in Romania in Spring 2023 and another one over Easter 2025. It's a great country with very friendly people and tasty food. I found driving there much more pleasant than in say Italy. You occasionally have some fancy German cars passing you at 150-180kph even on wide 2-lane roads (where the limit is 100), but the driving generally isn't aggressive, and we didn't see any highly dangerous maneuvres like passing in a blind turn. My two laments were traffic jams and poorly marked speed limits. Traffic jams might have been due to Easter, but it was insane. We spent almost four hours traveling OTP to Sinaia (should take less than 2 hours) -- 15-30 minutes at every roundabout on the Ploiesti bypass, half an hour outside Comarnic, etc -- apparently it continues that way through Brasov. On a peak day, I'd definitely take the train instead of going anywhere RN1. As for speed limits, most of the time I had no idea how fast I was allowed to go -- you drive for miles through a "village" where you're supposed to go 50 or 70, but the only indication is a sign with the name of the city/town posted at the city limits. Didn't see a lot of enforcement efforts, and no tickets in the mail thus far.
