From Emily Wolfe
I can see some advantages to driverless cars (16 January, p 20 and Letters, 13 February), most promisingly that they might spark a shift to ownerless cars.
An under-acknowledged blight is the land annexed by parked cars. If personal parking became a thing of the past, we might see a return to front gardens, with attendant wildlife, carbon footprint reduction and protection from pollution and flash floods. Demolishing garages could free up house-building space. And how much more free-flowing could traffic be in the absence of illegal parking?
It won't be a good time to be a taxi-driver, though.
