Putting into consideration how many times the system currently in place has stopped people from AR evading, I'm going to have to say that I do not support this suggestion. You'll get 4 AR evaders to 1 legit wanted blown up. Most of the time, you have the option to get the fuck out of your vehicle before you're blown to absolute shit.
I would, however, suggest the following modifications to the script, if at all possible.
Those exploded by ARMY lose their wanted level.
Those in an airplane during the explosion lose their wanted level. (This could be abused.)
Those exploded in terrorist explosion lose their wanted level.
