At least if the standard of design on lorries can be brought up it puts more and more of a focus on the operation of the vehicle as time goes on and gives less excuse for why a driver could end up running someone over.
The biggest thing that could be done as others have said is making sure drivers and cyclists know how to use the road safely but I don't see how this is possible without enforcement, because it doesn't matter how well trained someone is if they simply cease to care after passing whatever test or training they've had.
I think you've hit the nail on the head there, it is the arrogance of
some lorry drivers that needs to be addressed.
My solution would be to put the drivers position down to the level of a car drivers height, let's see how many other vehicles
some HGV drivers bully then.
BTW if you have never been intimidated by an HGV driver in a car, van, motorcycle or on a bike please feel free to comment, also one of my best mates has just retired after 45yrs as a 'Class 1' driver and he reckons driving standards have gone really downhill for the past 15yrs (along with wages)
