I have never driven a bus, driven many other vehicles but not a bus.
All sorts of aspects make controlling another vehicle very different from the usual one that we know.
I'd like it that all sorts of road vehicles were available for everyone to experience if they so chose.
But it isn't really 'necessary' if people have good safe behaviours on the road, however I do wonder if there are exceptions where some people cannot fully appreciate why others behave how they do and in fact for them feeling that experience will help them see how it feels to control other vehicles first hand.
Might this be, because people are less trusting of others intentions, and assume others are behaving selfishly and irrationally?
If more motorists tried to appreciate, sympathise, compensate for, giving space and time while the other motorists tries their best to deal with whatever it is that they are trying to do. Giving tolerance by patience and courtesy is far better than winding others up, getting in peoples way or even deliberately obstructing or antagonising others.
If people are noticing others selfish behaviours, are they so whiter than white, or might their own behaviours be as bad ?
This bus driver had a massive responsibility to all the other people who were his passengers, he has to have a very good spatial awareness as buses (as do lorries) need wide turning circles and lots of extra space and room to travel safely. It crossed every line of responsible and safe control of a vehicle & even more so of a public transport vehicle, to think of and then execute that manoeuvre.
