make a small steel box, weld the 4 sides, and the bottom, then fabricate a hinged lid which is kep closed by a pin which can be pulled out.
now, using the same principle of a handbrake, run some thin cable from the pin, throug the underside of your can and through next to your handbrake so you can pull it easily - this will the pull out the pin securing the box.
temporarily weld the box to behind your read bumper, upside down so the lid is at the bottom. fill the box with anything you think will burst tyres, i have a few 3d shurikens my uncle made, which is like a small ball with huge spikes on. or nails and tacks might work.
shut the lid and make some check, likethe pin wont come out by itself, the check the you can pull the wire with ease which will release the pin and open the box. once that is sorted go about your everyday life and if they come up behind you again speed up to temp them becoming faster (increases the risk of them coming off the road and hitting a tree) and when they are at a suitable distance pull the cable.
hopefully (in theory) at least one tyre will go, and at 50 mph thats enough to spin you.
this thread is in no way premeditation, just merely a way of copying james bond. whether you choose to ruin their car, its up to you
