Car Manufactures unite to develop campaign against car hijacking

Just a thought, since the spend for south african car brands is relatively high why do they not all colaborate & contribute a % of their marketing funds towards an anti-car hijacking campaign to get rid of those thugs who kill/rape/torture for the cars they are pushing to the SA market? Quite frankly every time I see a Toyota Run X ad or VW ad I remind myself NOT to buy any of those brands as they are high on the hit list.
