There perhaps should be a highly regulated frequency that is used for "Emergency - stopping dead now". With some localized physical coordinates (GPS possibly being the wrong granularity) so all within a certain radius know to immediately begin slowing, the closer the more radically.

RE: V2V, I'd like to see that car ahead of mine tell mine "hey, from my pov, there are people approaching, you'll detect them in five seconds --slow down as precaution. Same thing for things like black ice or object in the middle of the freeway.
Do you need that level of complexity if you simply slow down because the vehicle in front of you that detected pedestrians slows down?
What if there is no car in front of you?

Then you detect pedestrians as you normally would. I'm stating the additional vehicle to vehicle communication regarding pedestrians is overly complex and unnecessary.

No, rather it illustrates advantages of v2v comms. It could also aid merging to make it more seamless. Or, in cases of sudden stops or roadside emergencies, the car at the vanguard could alert the other cars trailing it of any upcoming driving conditions of interest.

Sounds like a hack waiting to happen...

Then nobody covers your field of view and you can see those pedestrians immediately and directly?

#17Blockchains allow transfer of value even between parties without contracts or deals or even trust, by exchange of a rare token. For eg Cars from different companies may negotiate among themselves using bitcoin, this was never possible earlier because for cars to exchange tokens theyd have to be under some central authority or some contract. Bitcoin provides the ability for signing contracts on the fly.. Another eg would be a car stuck somewhere opens a rescue request on a website. An automated crane bids and goes and rescues the car and goes away taking the bitcoins. For this to exist today some deal is needed beforehand.

There are many cases where this could be useful. Random one: let's say you're on a motorway behind another selfdriving car. It can see something: not moving, on the road, in the distance. Your car can't because the view is blocked. If the car in front is starting to slow down, then you've got two options - slow down as well, or start overtaking.
Without the extra information, it's a completely reasonable decision to start overtaking. And then you slow down as well, after spotting the same information. So yes - V2V would help here.

Only reasonable if 'defensive driving' is a curse word in your dictionary. Otherwise it makes sense to wait a bit and see if you can detect something too. BTW, Google reported radar working 'through' at least one car, it can look through the gap between the car and the road surface. And LiDAR can see through glass of a car in front, or just over its top (the sensor bump of the car in front down' cover much of you car's view when cars are separated by several car lengths).

The technical word is threshold. You're saying "wait a bit" - sure. Now you waited a bit and still don't see anything - you're going to start overtaking.
