Driving in Italy

Parking in Rome, don't, unless it's a scooter.
Driving in Italy: for Europeans, driving in Italy is in theory, a convenient way
to get around. Actually it's extremely stressful though high speeds
are possible if you have the right wheels. Read 'self-drive' below
and take the train!
Signposting in most places, with the exception of on autostrada
[motorways], is frequently irregular or non-existant. Rome is
particularly bereft of intelligent or sequential directions, so
the Bugadvice is get Italy GPS [SatNav] or let the train take
the strain.
While
rail and bus networks function well when they're not on strike,
the autostrada are scary places unless you're under 25 or an
F1 driver on a day off. Most autostrada are two narrow lanes with
trucks and low-power vehicles occupying the right lane apart from
sudden and rarely signaled excursions into the overtaking lane
where the rest of the traffic is travelling bumper-to-bumper at
160kph+ [100mph+]. Frequent speed limit signs are ignored.
The Bugforce was once, for example, in a tight 140kph convoy that
went past 60kph limit notices without noticeably slowing. Police
speed control appears to be out to lunch, though some villages
have green speed cameras that look like litter-bins that may work,
though the chances are not high.
The upside is that Italian drivers have excellent reactions, are
used to small spaces, high speeds and erratic last-minute actions.
They drive according to road conditions, not according to the
law.
Furthermore, if a visitor owned a powerful car in which the pedal
had never touched the metal, Italy [along with Germany] is the
place to give the motor a top-level thrashing; just make sure
the insurance in up to date and fully comp [and bring the car
papers too. If you don't have them the police can and will take
the car off you until you produce them.]
Finally, parking is complex, with different coloured spaces meaning
different things, but the worst thing is there are frequently
no parking space at all, underground or overground. Julius Caesar?
Pah! Short-ass Smart cars rule in Rome these days.
