I know nothing about modding, but I would kiss the forehead of any modder that can ease down on the hostile wildlife along roads. Bears and wolfs do not attack people on sight.
I wouldnt mind that they were there, they just need to run away - and if you then pursue or get too close they could attack you.

Moving this to modding section.

Cheers

Another thread is going on the topic of wildlife in this thread link: http://www.gamesas.com/index.php?/topic/1274840-animal-behavior/.

Nothing specifically on reducing spawns, but I'm sure that will eventually come up, as well as an increased spawns mod. I think it's pretty likely someone will end up releasing a detailed wildlife mod(s) for everything from more variety, less/more spawns, enhanced AI, and many other things.
