Discounting cultural aspects to most of our problems would be a mistake IMHO. I shall give a recent experience driving in India, where the roads were in excellent condition and traffic density was low. This was within the limits of Bandipur National park on way from Mysore to Kerala. Surprisingly, the the two lane road was marked and smooth to US standards, good shoulders on either side.
There were clear signs as well requesting people not to sound horns as it was an elephant corridor; despite that each passing vehicle kept sounding the horn at every corner or curve in the road, sometimes at the sight of oncoming traffic who was keeping to his lane and NOT veering into yours as is the customary Indian habit.
I asked my driver to not sound the horn, he kept to the instructions for a while and I noticed that he instinctively started the unnecessary trumpeting when others were heard doing so. I did not press him further with my ideas of driving within a park. Hordes of bike riders where v-rooming around too. Did not make a difference I realized.
Even the wild elephants seem to have adapted to Indian ways and were comfortably exploring the roadside vegetation with many onlookers on foot who had again violated posted rules which forbid them from getting out of their vehicles. There was a busload of people with small kids in tow who were running towards the hills to get the spectacle of the wild herd with their little pachyderms.
