Yes, but it's on a personal and one-to-one basis. There's no question that it's specialised, but its appeal, its X-Factor lies within the owner, and the owner itself. The specialized cars in question must appeal to everyone. Man and their cars are a very personal ordeal, whereas the cars EA mention must have a very wide audience.
And besides, what you're saying is the same as saying, for example, the Audi R10 TDi can only belong to the designer of the car, because it's his creation and idea. >_>
There has never been a NFS with fake made up cars and never will be. GTA and Burnout are completely different. No manufacturer would want you to shoot their cars with an M4 or RPG so they don't give Rockstar a license. Same concept with Burnout, no manufacturer wants to see those crashes happen to their cars. NFS has so little damage that no one really even cares.
