Well, maybe it's obvious that the pole of a street lamp is just gold-plated attention-space that's crying out for some media.
But, having zoomed out, you can see why it struck me that that the locals must be pretty good drivers to be able to focus on the three lanes of traffic decelerating on the hill that leads to a major intersection at the centre of this town, absorb whatever message was placed there
and avoid an accident. How long, I wonder, before some transgressor or victim sues the advertiser for distracting them while driving?
I can see the superficial appeal to insurers, garages and undertakers, but when assessing the location of one's promotion media, it's probably important to think about impact in terms of more than just effectiveness.
