Seminal paper on optically mapped, 3d space
The success of autonomous driving is limited by the sensors, typically optically based, that map what is seen in front of the car. Both distance, direction, and the calculated relative velocities are critical to guiding a car to avoid other moving and stationary objects. So this paper describes an improved approach:

Radar works by timing a reflected signal but the problem is sensor time resolution, they are too slow to achieve more than centimeter resolution. This paper outlines how to 'heterodyne' the transmitted and reflected light to achieve millimeter resolution. Better still, it appears to mitigate the fog problem.
There is a big gap between lab and product but the math and physics laid out here is the roadmap to improved, autonomous driving sensors.

Volt future
Source: AD #2259 – GM Pulls the Plug on the Volt, ZF Uses Blockchain For Car Sharing, Can Tesla Hit Its Goals? – Autoline Daily
. . . The data house [Autoforecast rjw] says the Volt will go out of production in 2022 at GM’s Hamtramck plant in Detroit. It appears that instead, GM is going to put all its efforts behind its aggressive plan to intro 20 battery electric cars by 2023. Even though the Volt was completely redesigned last year and sales shot up 60%, it didn’t last. This year sales of the Volt are down over 12% and fell 33% last month. Looks like GM decided it was time to pull the plug on its plug-in.
. . .
Whether it’s good or bad, there’s no company in the auto industry right now that can grab headlines like Tesla. The company has struggled building the Model 3. At the same time, it’s introducing new products like the Roadster and a semi-truck. So with all of that on Tesla’s plate, on the...
