And in a highly creative response to my yesterday’s “Unfair, unsafe and unwise . . . ” call for collaborative ideas for car control, one anonymous Scottish expert has just sent in the following technical illustration showing how they are able to slow down traffic and otherwise create a better smelling and more natural environment in Scotland.
