Most of Toyota's cars will talk to each other by 2025

From Engadget - April 16, 2018

Toyota is a bit late on the announcement though. And by the time its chatty rides hit the road, others will have already been deployed for a bit. Volkswagen specifically said its communicative cars will be on the road by 2019. A grid of cars that can talk to each other is something that's been tossed around for awhile, with the government granting the auto industry a block of spectrum in the 5.9 GHz band specifically for vehicle-to-vehilce (V2V) systems back in 1999. Toyota's implementation will use seven channels of that for its DSRC tech.

The idea is to start blanketing the roads with cars equipped with V2V and vehicle-to-infrastructure (V2I) communications, hopefully reducing collisions and traffic bottlenecks. But we are still a ways out from that. Three years ago, legislation was announced to make V2V systems standard equipment. But, that still has not happened yet. Ford recently announced its CoPilot 360 driver-assist suite will be standard equipment by 2020, but did not explicitly disclose if it had V2V communications systems onboard as well.
