There goes our park in HPP

[Aki]

Yes, some sort of barrier in the middle of the streets close to the highway that are currently being used as short-cut routes. The residents can sill exit off their street to the main roads out (M,P,K) one direction or the other but doesn't work nearly as well for the non-residents intending to cut through the park. How far down, street-wise, do you think commuters would be willing to travel before it's not worth their while in cutting across HPP?
