This sounds lovely but appears to miss a few points
-a lot of that stress is caused by commuting, which is an artifact of congestion. You could add more roads, but then "Induced Demand" kicks in: people do more journeys or move further out into the suburbs
-there isn't enough space in an EU city for parking either
-misses out on other pollution artifacts such as CO2 or NOx, the latter being tangibly harmful.
