World EcoMobility Festival in S.Africa - Should Lagos do EcoMobility?

I came across the World EcoMobility Festival which will take place in Sandton, Johannesburg and basically, people park their cars at home and flow only with public transports, walking. cycling e.t.c.

According to the festivals site:

The EcoMobility World Festival 2015 will take place in Sandton, Johannesburg – the vibrant heart of South Africa – in October. The Festival will offer a view of the City in the future, with active street life and social inclusivity, served by a sustainable transport system.

The Festival will enable residents and visitors from across the globe to experience what a future, car-free precinct would look and feel like.
A core part of the Sandton CBD use will be closed for regular traffic for the duration of the Festival. Residents, workers, the business community and visitors will, however, have full access to the entire precinct through expanded public transport and arrangements to encourage cycling and pedestrian activities.

So with the crazy traffic in lagos nowadays, should we imbibe some Monthly ecomobility or bi weekly EcoMobility where people don't drive for some time .. .?

Will it work in Lagos?
