Ive been doing this for over a week now if you want to seriously annoy someone on good sport grab a friend and each get a fuel jerrycan. Chase someone the pair of you kill someone in there car. One of you jump out to cover where ever he respawns why the other pours fuel over his car do a line to the rear of your car (Has to be a car with a backfire flame). Hold the hand brake and fully rev your engine to ignite the fuel line to whoevers car your blowing up. You dont have to pay any insurance and you wont be a bad sport. Another way I do it if im on my own ill wait outside the insurance place and keep blowing cars up. Also the car compound if you go to the roof of the multi storey carpark you can ramp in without gaining a wanted level and blow up any cars in there. Hope this tip helps from someone whos on badsport and wants to p people of who are in goodsport.
