|I have a single Banks a-pillar gauge in my f150. It's not distracting to me, but I think three of them would be. In a Z with more limited visibility out the front/side windows, I think a single gauge would probably both me.
I also hate bright interior lights a night. I dim the nav in my F150 all the way down. For me, I don't think I could tolerate several a-pillar gauges worth of additional light in my Z.
