I am probably the last person on this planet to give sensible advice on
driving in Europe. Be that as it may, I love driving in Europe. I drove
conservatively on the Autobahn at 120 mph (not kph) and 100-120 mph on the
Autostrada. It was a blast. In Italy you quickly learn gestures you would
have never imagined in the US. In Germany, you pull over quickly. Yet,
European drivers are far more courteous than they are in the US. They pass
and then pull over. They do not have the possessory attitude that US drivers
have with respect to the passing lane. They actually use their turn signals.
My suggestion is to pick up a beginners drivers manual and follow it
religiously in Europe. Having said that, you have to remember that I am a
Boston driver and as a Boston driver your day is not complete unless you
have scared someone to the edge of death.
