The commentary "Making cars take a back seat in urban commutes" (Nov 26) showed how far behind we are in the car-lite revolution happening in other leading cities.
Cities such as Paris have tried car-free Sundays; Oslo is planning to ban cars from the city centre.
We might find a total car ban too disruptive for people who genuinely need to use their cars.
Perhaps, we could start with closing off a lane on all the roads in housing estates for bicycles on Sundays. This might encourage people to leave their cars at home and use their bicycles instead.
For safety, we could reduce the speed limit for cars, buses and other motorised vehicles.
If cycling on Sundays catches on, this would contribute towards having cleaner air for everyone.
