All these roundabouts on the Lekki Expressway! Good or bad?

     When I first moved to the Lekki axis in Lagos, there were only 5 roundabouts up to Ajah junction. Now, I can't even count: there must be at least 8 now. However, I think that they contribute to traffic: the lanes around the roundabout are too narrow and there is not much organization. A lot of drivers do not give way to traffic on the left.
     I really think that they should have spent more money investing in flyovers (especially at Ajah junction), considering that they're taking tollgate fees from us anyway!! What do you think about  the Lekki roundabouts?
