There are small things in well run cities that people do not notice. 
I have done a lot of travelling into various cities or towns at night and after a long drive you appreciate small things that make life easier. I entered Cape Town the other day and I thought to count the dead lights. I got bored and gave up after around 150 - there were none.

It is the attention to detail that makes things work - maintenance with minimal disturbance is such detail.
