I think it is a given that you can create scenarios for every law that make the law look stupid.
I doubt that the amount of 9 seater cars with enough people inside is actually significant to recalculate the law.
The decision by weight is most likely done as this is a value which can be easily evaluated.
Assassins Creed 1&2 are not really open world games comparable with BoTW or ToTK. The world is much smaller and everything is far more linear. The combat system is also not extremely great. You can mainly just wait for counters constantly.
That said, I still enjoyed the games (especially 2) a lot. But it is more the fun climbing action and fairly good storytelling.
Skyrim might be possible, but I have not played it personally. The witcher is available on the Switch as well.
