In Norway one of the benefits of electric cars is free toll roads. But you must have an autopass chip for your car to be registered as free pass in the tolls.
When I installed my autopass chip, I did not know where to put it. Normally you put it in the front window. But I did not want the big panoramic window on the Tesla Model X to have any ugly chip on there.
Luckily from my google skills I found this solution.
I have done this myself and I got it installed and hidden. All the wonders of a Tesla. You always find more benefits. 馃榿
