I've seen plenty of pictures of ruined visors from this, so it's not just my opinion.

Some people are covering them up with other stickers, like this:
Visor Warning Label Covers 2008 xB
Import Car Visor Warning Decals. Designed to go over your current OEM Airbag Warning on your Window Visor. These will look great in your Import Car, Import Truck, Bus or where ever you want to stick it

Or, you can have visors reupholstered. I don't know if any Z people have done this, but on the vette forum a few people did this. They got matching leather. It looked pretty sharp, but obviously a good amount of money just to get rid of a sticker.
