> Why is nobody wearing a TT Helmet and visor on a normal road stage?

Because it doesn't work as much alone as in combination with specific aero body position. But you can't be in that position in a normal road stage because the aero handlebar extensions are forbidden in mass start stages.

Also there are less aero benefits to be had when you ride in the peloton behind other riders.

You don't need aero bars to have you arms forward and narrow. It's not particularly safe, but doable for a while.

The aero bar question (whether to have them or not) comes down to how long you will spend drafting and climbing. It's a more interesting decisions in Olympics and triathlons than most road bike racing (the latter it makes no sense because people are drafting as much as possible).

Arms forward and narrow, forearms on handlebar is a banned position of course :)
