Yes!!!
I have been searching my ancient files for a study I was peripherally involved with in the early 1980’s that was done by a team led by SRI (née: Stanford Research Institute) and Lawrence Livermore Laboratories. The study had physicists (fluid dynamics specialists), a Mathematical Biophysicist (Nicholas Rashevsky protege-As I recall) and an array of other disciplines. Multi-discipline everything was all the rage then, so even I was allowed to be there.
The board conclusions I remember clearly even though I don’t have all the paper.
Fluid dynamics explains auto traffic in nearly every case. High speeds without accidents are entirely possible, so long as there is minimal speed variation between ‘lanes’, nor movement between lanes. However, even a slight perturbation at high speed destroys smooth flow and causes accidents.
OK, obvious. But..
Slightly lower speeds, but with rigid speed stability, allows faster throughput without major risk. Further, reducing available locations for ingress increase stability as does increasing locations for exit. The entry/exit dichotomy was ruled true, but largely unexecutable. Parenthetically, there are a few highways designed with that in mind. They are almost all in formerly rural areas that have parallel access roads with more exit than entry options, but all designed to allow matching speeds to prevailing streams on access roads. There are a handful in the Dallas-Fort Worth area, some in various parts of Europe, China and probably elsewhere.
If FSD actually becomes practical, and fast acceleration becomes the norm it would be quite easy to optimize highways for very fast and efficient very close interval traffic. That is transparently the plan for Tesla Semi. It also already works in many parts of the world for dedicated bus routes. FSD can effectively deliver an exceedingly efficient, yet private, transportation system.
That has been the stuff of futurologists for decades. Will TSLA help make that happen? Obviously! Can we expect to make positive investments from this?
I hope so, enough so that I bet on it. Enough that I pay for the fantasy of FSD because the possibility of a positive outcome makes the expected value far greater than the actual cash outlay.
