Now Implemented!
Description
Offer a cruise control that is combined with brake assist and keeps the car at a set distance to the car traveling ahead.
Competitive/Pricing/Notes
You set the speed, say, to 80 MPH. Now a car changes into your lane, traveling slower. The Model S would automatically break to keep the distance and follow that car at that preset, speed-dependent safe distance. Once the car vacates the lane Model S would accelerate to the set speed again.
So convenient! I have driven rental cars that had it and from Seattle to Portland, OR, I never hit the brake or accelerator once! Just kept cruising along…
Many car makers offer this now.
It costs $2800 on a 2014 Mercedes-Benz E350 Sport sedan (but includes other safety systems). On a 2014 BMW 528i, it costs $1800 (but includes a rearview camera and other safety systems).
Status
Implemented in new cars made after November 2014 and with v6 software.
