You know you can do this on foot or on bike too right?

Part of the idea of a walkable city is that everything you need - nursery, groceries, parks, schools, housing - is within a 15 minute walk.
For the centre of Paris that is easily achievable for many.

I go a bit more often than I would have done by car, and I've started buying all my meat separately at a local butcher.
But it's amazing how much you can fit into 2 panniers and a rack.
I guess these central areas of Paris will become completely unsuitable to families, who will be forced out to suburban areas.
However, that's the sort of legitimate delivery that's actually a lot easier if the roads are not so congested with people driving themselves to work in huge comfortable 4x4s.
