The irony is that there is a sign on some of the buses advising passengers to use a their seatbelt, yet you can have passengers standing in the aisle.
I don't think that bus passengers are seen as important. The lack of an indoor waiting area at the Lerwick bus station being a good example. It gets bloody cold, and often wet, waiting in the open ended bus shelter in all weathers. A cafe, or the revenue for leasing it (or sale perhaps), was seen as a greater need than passengers being able to stay warm. This was to be fair, put out to consultation before the cafe was opened. Like most consultations the decision appeared to be a foregone conclusion.
There are a couple of benches at the bus station to sit on in more agreeable weather, but they are old and the varnish/paint worn away so that they absorb water when it rains. They stay wet for a long time afterwards, but no-one seems to be responsible for them and their maintenance. The trouble is that those who could make a difference, those who make the decisions, don't travel on the buses so they have no idea of the discomforts suffered by the travelling public, and apparenlty little care for the passengers either.
