Sure that sounds nice and all but it's just not at all a given in the way the character's powers are explained. You say he touches a person or car, these are the baseline examples, to launch them in whatever direction he pleases. Touch and launch. Same with Collapse and Rip, touch and break, and it really seems like he could readily pull people apart. You know, going by your own example of trying to launch someone's arm, since that limitation won't apply to those powers. Also he doesn't exactly need any brainpower to touch person and launch them or realize "I can throw things good to hurt people", especially since you say his aim with the gun-power is surprisingly good.
