This isn't a bug because in a lot of other games if you increase FOV your aiming becomes smaller. Downvote.

I have no problem with food or water. Almost every town/city has a water fountain and at least a little food. I do know the map fairly well so I know where to go and how long it approximately takes so that plays as a factor. Overall I don't think this is a bug or a huge issue.

I don't think raw input would be a good idea. I mean this is a simulator and having no mouse acceleration would make this game way to easy. It wouldn't be hardcore anymore if there was no acceleration. I got use to the acceleration but one thing I'd have to agree on would be the slow/negative acceleration It doesn't happen all the time but it is sure annoying.
