Yeah London's freeway network is REALLY underdeveloped for a city its size
True, and London can no longer get a freeway to serve local traffic. That time has come and gone.
This is just a vision of mine of where the 402 should have gone. In fact, the 402 was supposed to go through the city, not around it, but the city rejected all freeway plans. Most politicians consider London a small town, when in reality we're actually a pretty sizable city and the need for a freeway to service local traffic was always there.
There's also a urban growth boundary which does not extend to the 400-series (just a small portion along the 401 that has already been developed)

Regarding my freeway plan, there's a rumor that the MTO plans to extend the 403 from the 401 to connect to the 402 west of London. This will help reduce congestion on the 401 between the 402 and 403 and provide connections for areas north of London. Adding a freeway in west London and finishing the Veteran's Memorial Parkway will complete London's system, but the goal of these roads serving local traffic will not be reached.
