Good idea except unless they generator is right on top of target the pulse will radiate like a cone causing damage past the target, making it relatively useless in crowded areas. If they can make a tight narrow beam it will require a better aim and when you adrenalin is up that still leads to collateral damage. This will affect the people around the bad guys vehicle who have in the best-case scenario cell phones I-pods or other misc. electronics. Or in the worse case scenario the drivers with the pacemaker diving in the same area. Unless they have an insurance that will pay for all the electronics destroyed it won’t catch on, at least not in the near future.
