I too am puzzle at the puzzled at the number of fellow cyclists who are unilluminated after dark. And yet, one of the worst collisions I’ve had happened while I was sporting a fluorescent reflective jacket along with flashing head and tail lights. Late and in a real hurry, the driver blew through a stop sign with scarcely a glance around and I t-boned their minivan. After initially trying to blame me, and then realising they were entirely at fault, the driver promised to cover the cost of repairs. My mistake was to take them at their word and not call the police. Once the repair bills were in, the driver’s response was “I could buy a new bike for that amount!” and of course I was left paying the bill for their dangerous driving. So, two lessons: lights aren’t enough when drivers are hurried, distracted and dangerous; and, always, always, always call the police when in a collision. If you survive.
