"you could have a half hour commute to move 30 miles." Well unless half a million people try to commute along you during the same rush hour, with their commute ending in the wider centre of an old city which cannot absorb all the cars. In Prague it is quite common to spend half an hour to cross the outer 25 miles of your journey and spend another half an hour in the traffic jam of the last 5 miles. If it wasn't for the suburban trains and buses which alleviate the pressure, that last 5 miles would be one huge gridlock moving at the speed of a slow walk.
