Starting from Monaco '16 drivers can't throw their tear-offs out of the car anymore and as this is a technical forum, let's give them some innovative ideas (plus a few silly ones)
I'll start: connecting each tear-off with a fish line to a loaded spring on the back of the HANS system, so at the press of s button, they get automatically pulled inside a small tube.
An other system is like they use in motor cross. A role of film, with a cord to pull it past the visor.
