New 5 series introduction is next month, some reviewers got to drive a prototype. Has new autonomous driving features and will allow you to signal or confirm a lane change with just a head movement. I'm not really in it for the self driving stuff but this does look like an interesting evolution in the tech.
I can already get the car on semi-auto to change lanes for me. System works fine with clear lines on the road, which we generally don't have in Belgium. We do have traffic though.
System is also fine if there is a car ahead of you.
It will not work without good quality roads or a car to follow.
