Their purpose? "It's about a war we're waging. You see, our opponents give out around 4 times the CO2 emissions of ordinary saloon cars and are 9 times as likely to kill a pedestrian...they are the one and only 4x4s!
Basically, we want to stir up opposition to these cars. We want them to be frowned upon as the polluters they are. Well, what can you do? This is where the name starts to make sense...COUGH! Cough! To take part in our campaign, all you have to do is fake cough at passing SUVs and urban 4x4s."
Right On guys!
