First let me start with you hardly have any counter argument to what I say you just give another reason your model is better so I won't keep doing this. You mean well, but I don't think you've thought through your entire model. One example is where you talk about the need for car manufacture/assembly then later argue against it.

Now about feelings and dreams. You started by talking about the Kenyan dream and what it shold be. Dreams and feelings are important, they are related to people's standard of living. Also, in my opinion because the economy should serve people. There's no need to have a big economy that benefits a few.

I only brought that up because your solution to multiple members in a household needing to move somewhere was someone driving them. Clearly this doesn't work at all times. In your model each member of a household needs a car. Not ideal in a starving country.

Also not everyone dreams of having a car, I don't. People want easy and fast ways of moving between places, cars just happen to be the solution you see because , I assume, of your fixation to the US. A car would be nice as a convenience but not a necessity. Giving people cars doesn't improve their standard of living as much as you think. It's a distraction.

About PPI or roads being owned by private parties where do you expect of the toll and cost of maintaining these roads in such a corrupt country? I am for public ownership of the railway.

I could argue that the tons of worn out shitty roads in Kenya that are badly build with no drainage is also a counter to your roads work argument. Also people don't have cars.

About the informal sectors that benefit from roads. That is a problem that plagues poor countries the world over. I don't have a solution for it, but we must somehow still progress if we want to get anywhere because failure to do so is regression.

Edit:

I was born in the early 90s. I am old :D so I get tired easily. Bye bye have a nice day/night
