As an engineer, salesman and sales manager, I was on the road my entire 42 year career, doing around 35 to 40,000 miles a year, so I've been around and seen a bit.
Since the lockdowns I have watched driving standards dive with people adopting more and more poor driving habits.
In no particular order:
Pulling up to a junction and only looking left before pulling out.
Not indicating, or indicating so late it is a waste of time.
ME FIRST! Usually demonstrated by the driver coming towards you on a narrow road, failing to slow or stop until they are just about to hit the front of your car/ bike/ horse/ bicycle (I have experienced all of these on numerous occasions). But also often seen at junctions, where the Me First driver will cut the corner and sound their horn furiously at any vehicle having the sheer temerity to be using "their" road, regardless of the fact that they (the MF driver) is actually on the wrong side of the road.
Turning the wrong way. This is getting worse and worse. The driver who swings to the left in order to make a right turn (or vice versa). This even extends to roundabouts where a vehicle on the inside will suddenly swing left, across other lanes in order to reach "their" exit.
There are plenty more that could be added, and this is before we work in the ever present distraction of the phone... vape.... Costa coffee etc.
