That dreadful road..... they should build two extra lane which should be bus stop lanes. The entire stretch is a residential area.

One more thing I always ask myself, how about flexible working hours? Do we all have to report to work at 8 and leave at 5?

Good thinking but discipline on our roads is very poor. It is very unfortunate that we as a society tolerate the matatu industry to operate with impunity causing un necessary accidents. The poor discipline has been acquired by the new car/ middle class raising the question of standards in driving schools. Good traffic policing, proper use of lanes and road discipline is what we need for now. In the near future, road widening, underground trains and big buses will be a must.

Nyef nyef nyef nyef,...people love attacking the middle class for the aspirations to a comfortable life, as if attacking them is a solution itself. Rubbish. It is like those who have recently quit smoking, drinking, eating meat or started an exercise regimen ;They hoist themselves on a soapbox to lecture poor others who have not been so enlightened.
Bicycle enthusiasts, bus riders and tree huggers will not let 'middle class' have peace here.
Save your sanctimonious bullshit and try enlighten yourself a little.
Taxation by itself cannot offer lasting solutions - it is like a pressure system, when one point is squeezed, the pain and other effects move elsewhere.It is the tool of leaders who lack economic insight.There are many ills that can be cured first before hammering an already over-burdened populace. Like ensuring corruption free tendering for road and rail construction.
Policy makers need to lure citizens away from cars by implementing cheaper and reliable options - like trains and shuttle systems - not shuffling them at gunpoint towards a crumbling public transport infrastructure. Doing so will only leave them at the mercy of bus and matatu operators who will hike prices for super-profits
while lower income people get priced out of public transport.
Let choice rule. An analogy here was university education a few years back. Those who couldn't get places in the public universities shipped out to study expensive
courses abroad. Many families were under massive strain, but look now - a few competent private universities have emerged and I believe the number of students heading to the west
has reduced. Choice, not force. It is my firm belief that people in Kenya buy cars (even taking loans to do it) because there is no other viable choice.
Anyone remember those snaking lines for Double M buses in town?
In other places, it is not that people don't have cars, they decide not to use them for the everyday commute - because public transport is well developed. THEY HAVE A CHOICE!
(The UK has approx 35 million cars, a population of 63 million. The US ~250 million cars. Pop~ 317 million. Germany ~60 million cars Pop ~80 million. South Africa ~10 million cars Pop ~52 million
Lastly - we should curb our legendary impatience. This country has been going to seed for the last 30 years. Infrastructure takes a long time to take shape. In any
case your impatience and indignation won't change anything.

have you seen the way buses change lanes at roundabouts almost hitting the vehicles on the right lanes right in front of traffic policemen without any reprimand? what do you think that does when it comes to exiting the roundabout?

for those who have had the privilege to travel widely, are there traffic jams in the developed countries ?

Yes!
London ...with winds and sheet rain.
US too ...4+ lane one way roads notwithstanding

i totally agree, and even our sister city Kampala is no better

Most of the jams I have seen in North America are usually caused by accidents.
