I thought the way walking was handled made a lot of sense and worked well.
People are already accustomed to walking with the left stick and looking with the right. The right stick in this game is used for commands that involve moving the hands and it feels natural that way. So camera movement is moved to the left stick [minus R2].
Holding R2 while using the left stick doesn't feel weird at all. Unless you're a dude with some serious issues when it comes to 7th Gen racing titles.
