I guess you meant the car behind you.
It is called tailgating.
It is very annoying, I agree, but if I can offer en explanation, in those conditions to overtake you wanna cover the less possible distance, being closer to the car in front of you is a way to make it possible.
Having said that: compared to the population the most dangerous cities in Italy are, in order, Genoa, Florence and Milan.
That could explain it too.
To deal with a taligater, according to the experts, you should
> Brake slowly before stopping. Avoid tailgaters when possible by changing lanes. If you cannot change lanes, slow down enough to encourage the tailgater to go around you. If this does not work, pull off the road when safe and let the tailgater pass.
