I wonder if I should install a popup 30 sign on a rear window for tailgaters in the future.

  I'm curious as well, but I'm afraid they don't use such systems due to how they also keep distance as well as speed.

  Good thinking, but try a mirror. The majority of primate species don't recognise their own reflection, and the threat signals they display make them back off.

    But then you have the problem of cleaning the feces from that mirror.
