1. Nano titania filters, a UV illuminated volume, after the microfiber dustcloth large-particle filter inlets and reactive nano silver filters, for the mouth; same for the nose but with damp cloth filters too, for larger volume draws, in case something needs be smelt.

Sprung banners outside any rear panniers with waxed or superhydrophobic finishes all the way up to head height, and laserfoil (diffractive) finishes and automatic illumination there, in case of bespoke drivers; spares monthly just to stay shiny as a new, narrow bus?
