If you are a driver, you possibly agree that all pedestrians are slow, stupid and usually have no idea what they are doing. Imagine a pedestrian who just left a supermarket with five bags of stuff and trying to cross a road at about 6.30 pm.

This pedestrian is twice as slow (five bags of stuff, remember?) and stupid (after a long day at work) than usual. Therefore he is more dangerous and should be easier to spot to make up for it.

Here is an idea how to make this happen.

Most of the supermarkets offer free plastic bags to help people carry stuff they bought, and a lot of customers use them.

For a customer who goes home after shopping by foot it would have been safer to carry plastic bags with luminescent markers.

Supermarkets will only have to change the type of plastic bags they are providing in the evening (or some even in the early morning).

People carrying such bags would be much easier to spot on the road and, therefore, to avoid whilst driving.
