There's objective aspects of safe driving like leaving enough distance between vehicles (depending on speed) that are wildly ignored. You might get used to that in practice but that doesn't make it safer.
I was thinking about chaotic Italian road crossings. Or, to give another example, l'Arc de Triomphe in Paris. People tend to communicate with their cars where they want to drive and I understand that foreigners find this aggressive.
I was not thinking about excessive speeds or tailgating.
In Southern Italy, when you are stuck in a traffic jam in the city, you just drive nearer to other cars, and this is only mildly dangerous because you don't have high speeds.
If you don't drive tight enough, you just can't proceed because some other car will take your place.
