I think it would be a good feature to have if we were able to reset every spawned vehicle at the same time. It would save a little time for organized stunts or if you're carrying pianos in the back of a truck. Not to mention it would prevent the Tab, R, Tab, R, etc. that usually leaves a vehicle stuck inside another vehicle, leaving you you to do the cycle again. We have the debug functions readily available in the menu, but can't bind them to keys. I think it would be a good idea to add these to the bindinggen list so we don't have to use the menu to do things like Reset All Vehicles, or Remove Other Vehicles. It would be more convenient if these were bind-able.
