Back around '84 or so, my brother's best friend fell sideways under a dump truck and died. Narrow, busy, two lane road, it is theorized that he slipped off a rough shoulder into sand which stopped him and he fell into traffic. Dump truck rode over his chest and he died on the scene without ever being revived. It was a truly sad day in our house and town. Tragic, freak accident, no one sued anyone else. His father still does a commute of at least 12 mi one way, year round, and it has not stopped me from riding. Maybe I'm a bit more cautious where there's a low shoulder/narrow road situation.
