What new car could you possibly be driving where the wheels stick out farther than the arches? That's just another thing you have to know anyway, as 6677 said. You can't rely on passengers or assume anything as a driver. Assumptions cause car accidents. And are seriously that worried about rolling? You'd have a hard time trying to roll a new vehicle. You've obviously got access to the most accurate driving sim ever, so load it up, get in any vehicle and try to roll it on flat pavement. Good luck.
