Why is why the hardest word?

The Eddington report makes it pretty clear now that road pricing is inevitable. The only way, we are told, of easing congestion - by hitting you in the pocket if you travel on busy roads at busy times. Quite apart from the fact that this discriminates against the less-well-off motorist, perhaps the question which should be being asked is why motorists find themselves sitting in traffic jams on busy roads. They're certainly not doing it for fun! Could it have anything to do with the fact that most people work in towns and cities, and most workplaces start work and finish at about the same time? All things which are out of the control of the poor commuter, who is the one who ends up spending their time queuing to get to work and then again to get home, and who will now it seems have to pay for the privilege. Perhaps dispersal of workplaces and staggering of start and finish times should be looked at first?
