I watched a documentary on that Nyayo Car. The thing was basically just jua kali. None of the cars are the same and the engine looked like a messy car boot with wires. The car was so heavy, because of the thick steel sheets used, that some struggled to move.
They proved a concept and it was a good start. They should've just continued with standardised materials and processes.
In a place where thought is abandoned, freedom can become a curse.
