disadvantages of communication protocols

This here is one reason why Self driving or partially self driving vehicles might not be safer for some time. The communications between systems in self driving or partially self driving vehicles can often result in Byzantine Fault types of situations. Therefore, lives are at risk potentially whenever this happens. And since the driver (or potential driver) must be included in this Byzantine Fault situation this makes another layer of confusion or mis-communication possible especially in partially self driving vehicles.

Disadvantages[edit]

While the use of protocol layering is today ubiquitous across the field of computer networking, it has been historically criticized by many researchers[59] for two principal reasons. Firstly, abstracting the protocol stack in this way may cause a higher layer to duplicate functionality of a lower layer, a prime example being error recovery on both a per-link basis and an end-to-end basis.[60] Secondly, it is common that a protocol implementation at one layer may require data, state or addressing information that is only present at another layer, thus defeating the point of separating the layers in the first place. For example, TCP uses the ECN field in the IPv4 header as an indication of congestion; IP is a network layer protocol whereas TCP is a transport layer protocol.

end quote.

Also, just remember all present partial and fully self driving vehicles are communicated with over the internet in various ways. This makes it likely that at some point in time partial and or fully self driving vehicles will be successfully hacked and taken over.

If this happens to thousands of cars or trucks at the same time by say ISIS or Putin imagine the damage they could do at any speed when deaths inside and outside of partially self driving vehicles or self driving vehicles aren't a problem for the hackers!

Here is the movie I'm talking about. When I think about this one car would be hard to hack and thousands might be much harder. But, the point is I believe it is possible even though car manufacturers are going to try to tell you it could never happen. The point is "It could never happen until it does!" This is the best way to put this.

Mar 9, 2017 - But as unrealistic as it is, the scene probably won't do much to persuade people self-driving cars are safe. A University of Michigan study in February found that 33.4 percent of consumers are extremely concerned that self-driving cars without internal controls could be hacked and used as weapons.
