The private car/van drivers were VERY aggressive too.
The guy who took us to the airport drove as fast as he possibly could all the time(80+ mph) on the highway.
I sat in the front passenger seat.
My son and wife sat in back.
I really enjoyed the high speed trains. Especially the one that went 300 KM/hour.
We went to Rome, Florence. Sorrento and then back to Rome. Flew direct on Delta in and out of Rome to Boston.
