I noticed when using the outside car view, you can no longer spin the camera around. It wasn't smooth so maybe that's why it was removed? The other views however, the camera spins butter smooth.
They also added the 'Options' menu when you pause the game. Some new blips and bleeps I think were added for records/time.
For the brake thing, why don't they do what Forza does, add the brake line indicators onto the road (if you choose to have it)?
Also, does it look like textures or something is loading in front of you or just a bit ahead of you? It's so in plain view, it's hard to ignore, I hope they patch that sometime soon.
