I see that the City of London is introducing 15 mph zones and zero emission cars only on some streets. At lunch times there will be traffic free roads.
The City is very special place with 513,000 people cramming into the square mile every day. It is some time since I have worked in the City and the last time I visited, years after I worked there, the place was a very noisy and bustling. When I drove into London from the west once you got off the M4 there were not many parts of my route where you could go more than 15 mph. Bad days.
I find the centre of Ipswich a bit too crowded in my dotage so I try to avoid too many visits.
Edinburgh has joined the growing number of European and UK cities introducing lower speed limits. They say (Edingburgh City Council) that slower speeds bring many benefits to places and people by helping to reduce the risk and severity of collisions, encourage people to walk and cycle and spend more time in an area. The reduced speed makes it easier to cross roads, particularly for children and older people.
Suffolk lagging behind?
