Things I've learned on the commute is even if you wear high vis clothing, it's no guarantee drivers see you on the road. and when you commute on the cycle path when it's dark, there is a surprising number of dog walkers who wear all black and are invisible until 20 feet away (no street lights) and they quite like to let dogs off leads as it's "quiet at this time of the morning". had to park my bike up several dogs arses or between their ribs as they just suddenly turn into me or "chase me" too early. and I'm a dog lover too, just irresponsible owners.
This was a much bigger problem when I was on my Hybrid Carrera Crossfire 2, but since I've traded up to my Cube Attempt, the rear wheel clicks when you are not peddling, so I tend to stop pedaling as soon as I see them and the clicking gives them some form of heads up I am coming.
Rarely get a good attempt to beat my commute PB in the mornings, but it's still minutes faster than the Hybrid.
