“For cars, look at what new features the Mercedes Benz S550 is offering. The new features on the 550 usually end up on less expensive cars 10 to 15 years later. Think adaptive cruise control and the like. For reference, Mercedes had adaptive cruise control in 1999.”

“I have a Mercedes S580, and the augmented reality heads-up display is sweet. Like a fighter jet showing you where to turn, etc. The map on it does help, it’s not gimmicky at all. 

The adaptive cruise tracks cars you’re coming up to. It puts a little halo under them and looks like you’re locked onto another fighter jet. Pretty helpful in low light with small vehicles like motorcycles.

Coincidentally, I got rear-ended, and the car could see it coming and raised itself to keep me safe. Pretty cool feature. I’m sure some other cars do that, too. Safety features are developing so fast. It’s not so much that this or that feature is completely new, it’s how refined they’re getting.”
