The reason for the lack of vision among robocar visionaries

There are very few true robocar visionaries, the so called are mostly experts in a small domain who venture to make predictions on the entire large and complex industry.  There is no question that the V2V technology, (particularly DSRC) has been ready for several years now, however its deployment goes beyond technology, it requires entrepreneurs, investors, innovators,  policy, and regulations. We have not truly solved the perception problem, not to mention how wireless communications such as V2V can effectively work together with perception systems to improve safety and functionality of autonomous vehicles. For example, we still lack a proven technology that can fuse data from "all" types of sensors in a manner that increases the reliability and safety of an autonomous vehicle.  Yes, we also lack proven technology involving communications between vehicles and human drivers. As a whole, the robocar industry is extremely young and complex that needs much help from governments and this perhaps the number one reason that we lack vision among robocar visionaries.

I think it's going to take a while unless the government is willing to pay to replace all the older cars. I bought a new vehicle (with no autonomous features) in 2016 with the expectation that it should last me 10 or more years (my last vecicle was 16 years old at the time). There will be a substantial time lag between when self-driving cars are available and when a large percentage of the population no longer has older cars. The turnover will happen faster if the public buys in to the car as service model or if there is a way to retrofit older vehicles. I also expect that we will see gradual restrictions on human driving rather than an outright ban.

government mandating all cars be self-driving is going to be nere sooner than we think.  They still ned to address the network upon which these machines will communicate.  How much of a load these cars woudl put on it and other things.  But once they prove they are safer on the roads than manned cars human driving on public roads will be a thing of the past.  the car accident stats make it a priority.

This is the first time I have seen someone raise the latency issue especially with high speed objects. Good for Mr.Zyss.  My concern though is with the current update rate being discussed most is 10hz. That is not often enough. Two vehicles coming at each other in opposing lanes, with no median, at 75mph each would require 60hz to deal with last moment issues. If the first message reliability is not 99% and a second is needed the rate moves to 120hz. There are other scenarios which would raise it more. This community needs to looks at the most complex of threads in the worst of conditions and set that update rate. This of course will magnify the data volume significantly. Direct comms may be needed but those core update rates and data quality need to be addressed.
