Drivers are aggressive but not while driving. They can not shoot while driving, only passengers can do that. It might be possible to simulate it with constantly grabbing targets and making them shootAt but that would bog like shit not going to do that.
I'll see what phone options there are. I do know the events provided by SHDN to catch numbers being dialed as well as create new number handlers don't work so I won't be surprised if none of them work. But I will also look at the pure native calls and just entirely bypass SHDN and add them to my API class if I find one to put it into sleep mode.
