Is this really what got your back up? Just read the Lambeth transport strategy. This did not come out of the blue. It’s not being done for a single reason - it addresses a whole range of objectives. It’s about a transition to a lower carbon city, air quality, improving life outcomes by increasing physical activity, increasing transport capacity. Yes, there were elements that helped with Covid (and need for people to avoid public transport and not switch to private car or cab) but the plans predate that and it was never solely about that.
Now maybe the messaging didn’t try to communicate all of that at once but people do tend to respond best to simple messaging. Hands face space.
