That will be interesting because being transparent should have nothing to do with it. The system operates in the part of the electromagnetic spectrum that is not visible to the human eye. Take a look here
for a quick reference. Nobody in my family at least, can see microwaves, cell phone waves and radio waves
or the Jeep ACC radar waves for the matter...
My guess is that it will be senses as an obstruction (just like excessive dust, mud, snow, etc) and the system will give you an error. But protection is good when you are going off road. The slightest miss-alignment (such as when hitting a snow bank) will cause issues, including but not limited to false alerts, erratic braking or not working altogether. I've been there, done that. So...any protection is good off-road. But on road, with that cover on, you will likely not have reliable ACC operation.
