I believe that with the right set of laws coupled with proper enforcement, we can easily get rid of the absence of manners on our roads. Make it really painful to break the road rules and motorists will behave (suspended licences, jail terms, exorbitant fines and community service will do just fine).
I am almost agreeing with Mukiha that the money committed to Thika road was a waste - What with the "Akili punguani" driving on the wrong side, slow drivers on the fast lanes and a police service with no clue on what the traffic code says? Thirty billion was enough to do something more sensible than make half of Nairobi spend an extra hour on Thika road. Who is the Nairobi traffic commandant and why is he still on a payroll?
Earlier this week, I asked some traffic cops why they were letting motorists driving on the wrong side of the road get away with murder and they looked as lost as village boys in down-town New York. When I told them that the errant motorists should at the very least be charged with attempted murder, they looked genuinely bewildered.
