It'll be double sided tape, glued and bonded to the windscreen with a couple of rivets to hold the quarter inch steel plate welded to the frame and the electrified dog patrolled 10 foot high fence with the shark infested ditch around it (assuming the French let us use water this year).
You will also notice if you look through the windscreen how the red route conveniently stops, as I had a nice little red box to park in.
It allowed me to park safely after hours and Sundays. But it didn't stop me getting a ticket one Bank holiday Monday!
