I'd argue that. To many having to wear a motorcycle helmet or even a seatbelt is less dignified. As is road workers having to wear a reflective yellow vest.

Dignity is weird, some people consider school and other uniforms dignified, many others consider them an affront to free-expression and for them being forced to wear it is an affront to dignity.

If the goal is max dignity, perhaps pedestrian crossings should simply play here comes the chief or long live the king as you cross.
