New Garages on San Fierro

[MisterJohnson]

maybe extra feature that diverts the players around the map?

or, alternative method for avoiding excessive lag:
Y'know the part where you exit hideout/command post in NFS Rivals?
You get inside a private dimension until you drive some distance - say, 100m - to switch back to the main dimension.

that would be a most difficult and boring solution...

add garages is a method which already was programmed and applied in many situations, this private dimension stuff would mess up the whole stuff...besides, you're not passing through doherty only when you get out of garage, you may use it as a route to magazines and outruns...
