It seems most people now drive very aggressively and the roads have become an arena for competitive driving. There is very little give and take and its not often anyone gives way for anything. Even ambulances with their blues and 2's on sometimes get blocked in by inconsiderate drivers.
I have been driving since 1967 and the general manners of road users has got measurably worse in that time.
Unfortunately, what the lady driver experienced is commonplace and I cant see how things can improve much.
In my opinion, one of the factors in this behavioural decline is how much faster cars are now. Back in 1967 it was very, very rare to see a car than could beat 10 seconds to 60mph or have a top speed over 100mph.
Speed and its ease of availability is a factor IMHO. If we all drove around in cars that had top speeds of 90 maybe the pace of travel and its attendant perils would diminish.
And there speaks a man who drives a car that can almost top 150mph.
