Once when I was in one of those big rectangular oldsmobiles built in the 80s we were on the freeway and some guy a few cars ahead of us suddenly slammed on his brakes and everyone had to do the same to avoid crashing. We slightly rear-ended a compact car, the result of which was that it came away with a bent frame and we came away with a spilled milkshake.
Seriously, that thing was a tank.
