Tesla’s new ‘Speed Assist’ and ‘Lane Departure’ features use rearview mirror camera to keep drivers safe

A TeslaMotorsForums member found some new features in the new Model S 6.0 manual. The first, Speed Assist, actually captures speed limit signs as you are driving around and then tells you via the speedometer display how fast over the speed limit you are going. it also appears to geocache these from other Model S owners into a database from which Tesla can pull and confirm the speed limits.

The ‘Lane Departure’ feature is a little bit more useful (below). Like in some other cars, it detects when you are drifting into another lane and warns you.

Both features become available when the car is travelling over 30 miles per hour.
