I think it's probably an early teaser PV rather than gameplay.
・The license plate is "Tokyo Xtreme Racer", which makes it seem like a placeholder
・The FD, R34, and Supra don't look like they've been customized that much (the body kit looks like it's probably a reused one from Shutoko Battle Xtreme)
Based on these points, I think a teaser PV part 2 will be released next week.
However, there is some information that is known at this time.
A small truck that appears to be a Toyota Dyna/Hino Dutro has been newly modeled as an traffic car.
Take a look at the iconic front turn signals.
Another traffic car was the Mazda CX-3, which was playable in Shutoko Battle Xtreme.
The Supra that appears at the end of the trailer has vinyl on it, suggesting that the TXR2025 has a livery editor.
UPDATE: It appears that the body kits for the R34 and FD3S are indeed reused from the Xtreme.
However, these body kits may just be placeholders, so we don't know if they'll be included in the final game.
R34 body kit: Note the distinctively designed small duct located below the front duct and the equally distinctively designed black splitter.
FD3S body kit: The two images have in common the distinctive large canards and the lip spoiler with a large recess in the center.
