In large cities, there are many perils for pedestrians: cars, bicycles, motorcycles, horses, etc.
Even the sidewalk is not a safe zone from scooters and bicycles!
At night, the problems are even worse, since pedestrians are generally un-illuminated and are frequently wearing all-black coats in the winter months.
Since many commuters carry a laptop bag, briefcase, or purse, it would be easy to put some sort of high-visibility indicator on this object: for example, an LED light (see animated designer laptop bag in Figure 1).
This would be less intrusive than wearing a high-visibility vest, and might be an easier sell to fashion-conscious commuters.
Figure 2 shows the same briefcase as a still image.
This is clearly the next evolution in fashion: reserve your designer laptop bag now!
PROS: Should reduce pedestrian fatalities and the city’s overall fashion rating at the same time.
CONS: May make your coworkers jealous and cause them them to plot against you.
