Shooting at a moving car is a no-no because it doesnt stop it and can cause more damage if you hit the driver and they lose control

Pointing a gun at anyone you dont intend to kill is as well

Seeing this coincidentally. I may be wrong about the immobilizer but even having one aspect of the car fail could cause issues if the person isnt expecting it, especially if they are already speeding. Also theres no saying if there could have been physical sabotage to the car or that he was driving something with issues like a recent honda (steering rack issues that cause them to lock up)

Cars don’t explode like in movies

It’s also a huge vulnerability that modern cars have internet connections and could easily trigger the immobilizer or drive it into a wall
