By all accounts, 67-year-old Harry Fenton was a model of safe cycling. He used hand signals when he was turning and stopped at every stop sign and red light, even when there wasn’t a car anywhere in sight. To be visible, he wore fluorescent jackets, vests and shirts, and he never left the house without his helmet or fully-charged lights. He found routes that felt safe and then stuck to them. Fenton, in other words, did everything right.
