Or, one might use caltrops. I used to fantasize about having small caltrops that I could throw under tires of vehicles that cut me off or drove too close while I was biking. Place some a little ways in front of the tires so that when the vehicle took off, it had some momentum to drive the points into the tires.
I think you are describing roofing nails. But realistically, you don’t aim caltrops and you are almost assuredly only going to create collateral damage.
