greener autos to Grateful Dead-themed cellphones -- most of which don't really ask us to tone down our consumer impulses all that much. But how about these new "Cool Cars" regulations recently adopted by the California Air Resources Board? By the year 2016, all autos sold in the state must have windows that prevent 60 percent of the sun's energy from entering the vehicle. To achieve this, windows are given a coat of glazing that contains microscopic specs of reflective metal oxide -- which will seriously hamper reception for your GPS, cellphone, and (this is of special interest to Engadget readers) white collar criminal-style work release ankle bracelet. As you can imagine, companies like Garmin are fuming -- although we suppose that if they play this right they can make a killing in the external car antenna business. It just goes to show you -- when it comes to environmental catastrophe, everyone's a victim.
