driver assist package on range rover sport

I took delivery of my Supercharged Dynamic last month with the drivers assist as standard equipment. Hopefully, I won't ever need to describe how the high speed, collision avoidance emergency braking works but I think this feature along with adaptive cruise control, and lane departure warning, especially if you do a lot of high speed highway driving in moderate to heavy traffic is essential these days. Somewhat surprised these features are not standard on all models, especially on a vehicle in this price range.
