The Barnacle — an opaque piece of plastic held in place by two suction cups and 750 pounds of force — makes it nearly impossible for a driver to drive away, even if they think they can cleverly stick their head out of the window.

Held in place with suction cups. Which means that a small drill which makes a hole in the plastic (but hopefully not hitting the glass of the windshield), thus allowing air in and breaking the suction, will make it un-stick.

Carry around a .005” feeler gauge and slip it between the glass and suction surface.

Just put a plunge-depth stop on the bit and no problemo.

Years ago when they developed the boot I fed my money into the wrong slot and came back to find my vehicle booted. They refused to believe that I had paid and told me that it would be $50 to unlock the boot. What they didn’t count of was that I had heavy-duty bolt cutters. I called them up and offered to return the boot - for $50.

The device is likely very hardened and can’t be drilled with hand tools.

But you can always drill a teeny tiny hole from the inside of the windshield and then patch it with a drop of epoxy.

My first thought.

Any damage to the barnacle and you’ll be buying the a new one plus extra fines. The physicist in me says you could heat the glass under the sucker on your windshield on the inside with a micro torch or maybe a even a cigarette lighter and probably pop it off.
