Los Angeles (more correctly the Southern California Transit District) decided that the city needed more shade at bus stops. Poorer people and immigrants normally use the bus in LA, because few people don't have a car. And extra shade is a great idea. As you might expect, the busses do not run often.
But the implementation is also important. And implementation here is laughably bad. The "shade" is riddled with airflow holes, and therefor doesn't provide much relief. And the "shade" that it generates will cover, maybe, one person. It does have light for safety at night, but past that it is a bad idea.
Giving the designer the benefit of the doubt, perhaps the new shade had to use the existing pole. In any case, it is pretty pathetic.
