Taken together this means that you can generally go pretty fast in the leftmost lane.

Then you also have the special letter of the law crazies who zig zag every minute across multiple lanes to pass people in the middle.

On designated one-way streets, and thus not on motorways, passing on either side is expressly allowed. Of course, reckless undertaking at high relative speed on the motorway may be interpreted as illegal under other more widely encompassing laws.

This isn't the US. People aren't driving on the left lane just because they can.

It does to me.

Edit: typo corrected.

Seems you've never driven in Italy. Let me assure it's very possible. In fact it's just matter of fact!

Even when going “just” 200-220 I often get passed by cars that are going much faster. With three lanes this is not a problem.

It's national highways (kinda like "interstates") from Padua to Rome (something like Portland, Maine to New York), not some city roads.

Unlike in the US, in some European countries like Italy and Germany you have very high or unlimited (Autobahn) speed limits, and roads good enough to maintain them.

In Italy the autostrada legal limit is already higher at 80/130 (and supercar drivers frequently go much over it).

And of course this is the police, they can make an exception for themselves :-)

If they were closing the roads ahead, or if the driver was like a racecar driver it's totally doable with a bit of luck. If they did both it's even like, reproducible.

Edit: the Huracan seems to have a 90L gas tank, divided by 480km they must not have exceeded 18.75L/100km in one go (= 17.33mpg). I.e. they must have refueled at least once, if not twice

You're going to have a bad time on the Autobahn if you think like that (which is not in Italy, sure, but "highway" etiquette should apply to both cases)
