When driving on a 2 lane divided highway, the maximum speed could safely double as long as the width of the highway increased 2x. The trouble is that this is not always practically possible due to need for reduced speeds (ex - accident ahead). This is why the number of lanes should not be fixed, by
dynamic.
These would be the modes:
-Single wide lane, 200KM/h
-Two lanes, 100KM/h
-Three lanes, 50KM/h
-Four lanes, 30KM/h
Switching between these modes would be controlled by an algorithm that takes safety, weather and current traffic level into consideration.

Anyway, at 200kph there's only one lane, so you're not allowed
to overtake. So there you are, stuck behind someone crawling
along at 180kph. Remind me, what's the safe stopping distance
at that speed? |

I wonder if something like retro reflective e-ink could be used to make the lane markings. Tiny hollow spheres containing magnetic hemispherical reflector beads. Embedded conductive paint or wires could produce magnetic field to flip them around to switch the lines on or off. |

Super. So the only problem left is how to manage the transition points. Does the lane markings suddenly switch from two to three, and all the cars swerve in a panic, or are there set "transition zones" with the new laning propogating forward at the advertised speed? |
