If you could put all NFS' cities combined into a single map

That's a great map, you actually inspired me to make one like it. But I'll tell you this: I'd have more connector roads leading to the different boroughs/ cities/whatever you wanna call 'em. Here's mine:(note: This isn't really connected with how I think NFSU3's story should go, it's just a separate idea.)
The white district is called Temple City, where the player starts out. It's got afew highrises around the south side, a pro football ( American football ) field, a decent sized residential area, an outlet mall with a big parking garage/parkade, a beach and some business districts to the east. It's a suburb of Port Neson, and it's based off of Ontario, CA .

The yellow district is the Port Neson International Airport, it's accessible at the beginning too. It has 2 large parkades connected to eachother and a runway where some events take place. It's based off of LAX in L.A and McCarran International Airport in Las Vegas.

The red district is Port Neson/City core. It's the 2nd place that the player can unlock. It has TONS of highrises, a MLB Baseball field, an indoor arena, abunch of jumps and parkades, and some cultural districts like Chinatown and Little Tokyo. This is where most of the action happens. It's based off of L.A and San Diego.

The green district is called Fort Hewitt. It's the 3rd area that the player unlocks. This is the industrial area in the city, it has an oil refinery, a dockyard, some factories, a small residential area and some construction. You can jump from the dockyard to the aircraft carrier and then onto a pier to get to downtown or you could just take the freeway bridge. This area is based off of Baytown, TX and Coal Harbor from NFS Underground 2. There's alot of action including new cars being imported and new performance parts coming in from overseas.

The pink area is called Redwood. It's the 4th place that the player unlocks. It's the rich district with an old downtown area plus a canyon route. The old downtown is based off of Henderson, NV and the rich residential area is based off of Santa Monica and Beverly Hills. There's racers from all around in the old downtown and the ones from the rich side of this area tend to be stuck up and hate outsiders.

The gold area is called Los Senderos. It's the last area the player unlocks. It's a smaller city next to Port Neson. There are lots of casinos, highrises, malls, and there's also 2 legal tracks, a NASCAR type ring and a drag strip. It has a residential area, some business districts and afew jumps. The scenery around here is more like a desert despite how close it is to the ocean. It's basically right over the hill from Port Neson. It's based off of Las Vegas but its location isn't correct exactly.( If you look at a map of Los Angeles, CA, there's a town called Lancaster, not very far away. That's where Los Senderos is supposed to be located in relation to Port Neson on my map. ) There's alot of action here over the mountain from Port Neson, almost as much as in the city core.

There are afew roads leading out of the city, they're supposed to lead to the cities from other NFS games.
