This week’s instant classic by our national treasure cartoonist speaks for itself.

But in case you need the background, our colleagues at Streetsblog USA have been writing for years about America’s failure to rein in excessively large automobiles, which are the main cause of the 50-percent increase in pedestrian deaths since 2009. So here’s a bibliography of all the stories you should recall:

• The feds’ vehicle assessment standards don’t care about anyone outside the car.
• Cars and SUVs are indeed getting safer … for their occupants.
• Study links the rise of SUVs to the pedestrian death crisis.
• The tortured history of the federal government’s failure to address road violence by big cars.

And, of course, all of Bill Roundy’s cartoons are archived here.
