HUD won't protect from a driver texting and running you over!

What will protect is taking bicycles off motor vehicle roadways, and laying down new, much narrower bicycle-exclusive roads all over instead. It doesn't make sense to mix the slower and vulnerable bicycle traffic with the faster and safer motor vehicles!

Neither will anything else, so that's not really a competitive disadvantage.

Well, a wall will. It might even dissuade them from trying.
