Are they willing (or have they indicated) the power output of the laser?
(Seems a bit weak; beam width). Can we find out what type of laser and 
wavelength?

Seems possible to build a "jammer" for this by flooding the area in front of
and behind of your car as you book to work/play.  (Assuming it can be done
safely)
