It always makes me laugh when I see “Sports Utility Vehicles” filling up the car parks of places like Aldi and Lidl - where the fuel spent to get there - probably outweighs the 50p saved on the tiny basket of shopping these morons end up buying from said establishment… 
Why don’t people with larger cars - buy a whole large shopping trolly of stuff WHEN they decide to “burn some fossile” going out to get the food shop in?
It’s like hiring a luton box to bring home a stereo you’ve just bought!
