How do you know the guy was commuting? Could have just been out for an epic ride, bonked and got home late.
I've been caught out a couple of times over the years heading home without a front light when trapped at work for longer than expected. Not a great situation but it happens. I commute 15km each way 4 days a week on 50% shared path. Consistency of lighting on bikes is HEAPS better nowadays than it was 10 years ago, due presumably to improvements in lighting system availability, quality and pricing.
After dark, 95% of pedestrians on the shared paths I use have no lighting or reflective gear either. They present as much of a challenge as a rider without lighting.
