I doubt the entire games would be exclusively day time or night time depending on the version, but I think it's possible that there could be a period in each game when the day/night is forced to be permanent. Kind of like how in RS/ORAS it became constantly sunny or stormy when Groudon/Kyogre broke free. The legendaries in Sun and Moon could become enraged and force the world into a state of permanent (until you fix everything, that is) light or darkness.
As for driving, that would require A: a large enough map for it to be feasible (unless it's just a cutscene or something) and B: a canonically older protagonist (maybe 16 or 17 years old). I'm not saying it won't happen, but I would consider it unlikely.
Otherwise, GTA Pokemon, rated 18+, coming Holiday 2018 confirmed
Hmm... would they do a fire snake? Serperior is already meant to be a snake, so I'm sceptical that they would repeat the animal within only two generations. Correct me if I'm wrong, but I don't think they've ever so far done the same animal base for starters twice (with the exception of Squirtle and Turtwig, I guess).
