Renault (also Citroen and Peugeot) have an optional "heat reflecting windscreen" designed to keep the heat out - the blue tinted front glass. In theory this would be relatively opaque to an IR camera as that is the whole point - to block non-visible radiation.

Apparently they block both IR and UV but I don't know how well - there are reports about GPS signals being blocked by these windscreens and the need to use a re-radiating antenna in order to get reception, but they refer to the UV side of the filter which is at the other end of the visual spectrum. You can however get aftermarket films that work at 99% for UV and 95% for IR. So blocking the IR cameras from seeing the driver is perfectly possible.

I bet the take up of this option becomes popular when this little flaw in the Gatsos technology comes to light!
