Great parking lot and terrible stair lighting

On a recent evening in Dresden, I noticed some great area lighting in a mall parking lot. As you can see below, the visibility in the parking lot is excellent.

In this closeup focused on the luminaires you can see that these types of lamps send almost no light directly up into the sky and are not at all glaring. Why isn't every parking lot in the world lit like this? Beats me...

Of course, it's impossible to tell by eye how bright it is. It's possible that these lamps are putting out more light than is necessary. It's also possible that they should have a warmer color. Regardless of whether these lamps were perfect or not, it's clear that they are excellent compared to the typical parking lot!

While I was visiting Dresden, I also noticed another example of how additional light can make your vision worse:

This lamp is intended to help people see, but it's right next to a stairway that is completely unlit due to bad positioning of the lamp! You can see how invisible the stairway is in these two photos from roughly the same angle:

In this case, you would actually be better of if the lamp wasn't there, and you were just navigating by artificial skyglow or moonlight.

Finally, a little contest. Comparing the last two photos, can you spot another lighting problem? Answer in the comments.
