Minecart player rotation

Its good to have rotating player camera in minecart while turning, but the intensity of turning speed is very high. I had set up a small test area with many turns and sat in the minecart keeping minecart speed to default. After sometime i was feeling dizzy and my head was starting to ache a bit. So my opinion is that o reduce the player rotation speed and make it more smooth (not as smooth as cinematic camera smooth), but it should be subtle and feel should be like real head turning.
