Public transportation in Italy is excellent. High-speed trains connect major cities, traveling at speeds of up to 150 mph, while slower regional trains connect towns with a small population. Even tiny villages have bus routes, although there may only be one or two services per day in either direction. Driving is not for the fainthearted, since Italian drivers can be aggressive and can change lanes or directions without warning. Italians drive on the right-hand side of the road and use their horns frequently.
