There are certain situations and driving behaviours that are more likely to lead to angry and frustrated drivers than others. Some road layouts can result in anger hotspots, with drivers quick to jump to the conclusion that they are somehow being done an injustice by the behaviour of other road users. But usually there are some very simple rules that can help nip any frustrations in the bud.
The RAC says that hogging the middle late, not letting you merge, and merging at the last minute are some of the main factors that are seen as being "aggressive and dangerous" on the roads.
They say: "All of these and more seemingly innocuous driving mistakes can still trigger aggressive responses from other drivers. There’s a degree of separation that happens when we’re each in our cars as well - this can embolden drivers to show much more hostility than they would if they weren’t in the isolation of their own vehicle."
