I'm not a fan of the pre collision system. I'd love to disable both and not have dash warning lights.
All it takes is one deer hopping out of the bushes in front of you late one night on the highway. Truck stops RIGHT NOW. Like, before you can even get your foot off the gas. Seat belt tensioner engages, holds you back. Saved me twice. I'm OK with that. I wish my Miata had PCS, it would have saved me from having the front end replaced last Fall.
