Have you ever paid attention to ... (Need for Speed: Underground 2)

Have you ever noticed that there is a big weirdness on one of the drag tracks ... The drag is called Bayview Bridge. Doesn't it seem strange to you that we enter this bridge through the tunnel and there are trains running on this bridge from both sides (!) And the city center, to which we reach completely different !!! Other houses, by the way, similar to the houses from NFSU1! As if it were a different city! How to understand this ???
