So most new cars come with some sort of lane-keeping “helper,” how about one that would actually help?

Camera detects the presence of a solid painted line to the car’s left, indicating that it’s in the left lane. Super-smart computer compares vehicle speed with the speed limit in that location (using GPS or whatever).

Plug the following into this nifty algorithm:

S= vehicle speed, SL= present speed limit

If S<SL+10, activate dash warning:

GET OUT OF THE WAY YOU FUCKING MORON

Then self-steer into the right lane where it belongs.
