Is Jonathan Chowns (Letters, November 11) living in a dream world? A car-free city?

He is obviously young and fit. My late husband, who died aged 56, was disabled and unable to walk far, let alone cycle. He relied on his car. There must be many others in the same situation.

I am an ardent walker and have never driven but let's be fair, some cars are essential.
