I imagine there are all sorts of ways to make a car break down - from adding something to the fuel, putting a cut in a fuel line or brake line, etc. Of course then you don’t
if the breakdown won’t be in a well populated area.
Probably pretty easy to rig something up with a remote control too. Take a small radio control toy car, replace one of the wheels with a small circular saw, bungee cord it to a brake line or fuel line. Follow the truck and wait until you are 30 miles from nowhere and turn the toy truck on. (Hmmm - that might actually work!?)
Of course I imagine armored cars get inspected and/or are guarded at every stop.) Like the earlier thread was saying - probably an inside job.
You seem to know a lot about this.
Yeah ,
where were You at that time?
