Secret teleport area!
Use the perfect traction cheat, then get killed in portland or head to the portland hospital. Look across the street and you should sea an alleyway with lots of garages and a hidden package. Take the car parked there and drive it out into the street. Point the car towards the alleyway and drive as fast as you can. Just before the wall press L3 and your vehicle will jump over the wall and fall through a gray area. After a bit of falling your car will spawn in a random part of portland. Usually the few blocks around the hospital but I have ended up at 8-balls bomb shed. Happy teleporting!
