Glad you're ok and got away without any issues.

If it comes down to it in that kind of situation, if they're blocking you from front and behind just ram your car past the car blocking in front, you'll wreck your car pushing their car out of the way but the kind of people who do those sort of robberies are dangerous and likely to hurt you in the process. Just try not to run them over because then you're the one that gets in trouble. fighting a manslaughter charge will require expensive lawyers.

If you come across things on the road meant to puncture your tires in an attempt to make people stop so they can be ambushed and robbed just drive over it.

You'll get far enough on flat tires to get to safety as long as you don't lose control because of uneven handling.
