It's a highway in the middle of a concrete jungle. It's meant to look that way. If you grew up with the Shutoko Battle Series (Tokyo Extreme Racer as it's known in the Western world) and watch Wangan Midnight and play the Maximum Tune series, these tracks hold a lot of significance. In previous games we have the Special Stage Route tracks which tried to ape Japan's highways, but Tokyo Expressway is a lot more realistic in terms of scenery. Unfortunately the layouts are not exactly the same as in real life, but that's probably because PD wants to avoid direct street racing comparisons.
^You can see the inspiration for Tokyo East's esses in the last video. The looooong straight and tunnel is based on the Wangan Line. Tokyo Central is based on some parts of the C1 Loop. Tokyo South is a bit hard to place but the docks area is reminiscent of Yokohama and the pit building is based on a real life building too.
Yes they're bad for pack racing, but you gotta remember the street racing that happened here in the 90s was mostly between 2-4 cars only. The main challenge is how precise you can be driving between those walls, and avoiding traffic (obviously not something we have in game). At night with billboards and neon signs from the nearby buildings, it doesn't look so bad. But the problem is most of the time of day options are at daytime and most of the races we have are also at daytime, which contributes to the grey lifeless look. It's fine, it's realistic. Not every track has to look like Kart Space. In fact, most real life circuits also look pretty dull during non race weekends without spectators and all the banners/flags/etc.
Basically, if you grew up with tuner culture, these roads are as significant as any famous road race in the world (e.g. Pikes Peak, Isle of Man, Mille Miglia, Targa Florio). The only difference was the racing wasn't sanctioned. I'm in no way condoning street racing, but at least this way we can imitate that safely in a game environment. Are they the best fictional tracks PD ever made? Definitely not. Am I glad that PD decides to add them? Yes.
Hope that helps explain why some crazy people like me like to drive on these boring, grey, lifeless highways
