@MichaelHarvey Some people write on phones, the phone's autocorrect will choose VISA over visa because people talk about VISA cards more often than they do about actual visas.

Also an addition to the #1: These seats are almost always at the same elevation as the bus "floor", so that you don't have to climb up or down on the bus. Especially important for elderly with weak knees and pregnant women. (in comparison, most other seats on our buses in Turkey are elevated for some reason or another, usually due to technical limitations of the bus design)
