More "track secrets" that I can recall:
- Licence test IC1 shows a wet version of the Top Gear Test Track at a time of the day apparently different than usual. Yet, we can only select sunny conditions
- The visible oval section at Monza seem to have more detail than what is usually seen on secondary track scenery. Possible hint to a future usage of it?
- The misterious SSR7 scenery concealed by anti-noise panels that are all over the track. In my opinion the track has not been completed yet (it's clear especially when running it in reverse), and when it will, the panels will be dropped on most of it.
No, there currently are no night racing tracks, except for Special Stage 5 and 7. What's weird for those track is that the selectable versions have the "Night" suffix. I think that might hint the possible inclusion of other tracks in night time only (not changing time). I'm thinking of Tokyo R246, or Rome (Rome Night!), for example. All city tracks could potentially have night racing.
Suzuka, Tsukuba, Daytona and Laguna Seca also are supposed to have night time racing, since there are in real life. These are not original tracks, though.
