Admittedly, I don’t take the train or bus anywhere near as much as I used to, but when I did there were always poster adverts about being respectful towards other riders and staff. Have those gone away, or is it that there is another influence supplanting that messaging?
Perhaps phones being much more engaging that people actually spend a lot less time reading the PSAs and adverts around them?
In a weirdly similar way, I remember pre COVID there used to be so many more drivers that would be blasting music with their windows down that it rarely deserved a second thought. It’s much more rare to hear it nowadays, to the extent that when I do, it seems so much more obnoxious.
Silly one, and but do tanks run on diesel?
Every other heavy machine I can think of typically uses diesel for their engines: tractors, lorries, boats.
Also diesel is less flammable then petrol or hydrogen in the event of a spill of leak…
