Tell us how you really feel! I don't think anyone is arguing that it's impossible for a person to cross the road, but that on balance a crossing between the two current ones is justified. For the elderly, parents with young children, the disabled, and unfortunately for the dangerously impatient who make the road more hazardous for everyone. Taking your argument to the nth degree, you could argue the crossing outside Iceland is superfluous because people could cross down by the Plough.
