I lived in an apartment in a heavily congested area when I was young. You could stand in the parking lot and see the grocery store but it would take 15 minutes to drive there.I'm happy to find that there are now more upgrade centers in the Greater Los Angeles Area and one is roughly 1/2 hour away from me -- or two hours, depending on traffic!
I have a feeling both the P3 and Radius upgrades were only made available today, so the retailers may not have known about it until very recently.
