My first post of 2012 and turns out it's another rant. Oh well.
My apartment building has multilevel underground parking, which is good; each and every corner, however, is a blind corner, which is bad. When I first moved in I noticed some residents would honk as they approached a corner, which is good... in theory. Why only in theory? Two reasons, one perhaps slightly facetious, the second more dangerous.
What happens if you're leaving and you hear someone honk? What do you do, honk back? Do you both stop, honking one after the other while you each try to figure out which direction the other is going, what level they're on? Shave-and-a-haircut... two-bits!
More seriously, though, is that too many use honking as license to drive too quickly in the underground parking. Just because you honk doesn't mean you can blithely cruise around two successive blind corners at 30+ km/h.
Fortunately, management has now placed convex mirrors on each and every corner, which is good, meaning that in practice there are no more blind corners. The bad? Some drivers are still honking (look at the mirrors, already!) and speeding like if they don't gain a minute on their day they'll lose a million bucks.
