That's not going to happen, not in our lifetimes. It's not safe to do this unless you have a critical mass of cars on the road capable of doing it. Given the average age of cars, it'll take ~10-15 years from such tech being mandatory in new cars to think about doing this. Being mandatory is of course itself over 10 years from it being available. And it's not available yet.
We're now a decade out from people starting to say "stop investing in public transportation because driverless cars will obsolete it," and so far driverless cars have only managed to provide a limited taxi service in a couple of cities, a far cry from deprecating public transit.
(Actually, I personally hew to the belief that driverless cars will make traffic worse, since it will probably increase the number of empty cars running around because traffic tends to be dominated by unidirectional bursts of traffic.)
If the car ahead of you is sharing visibility and braking data, you can drive on their bumper and stop when they stop.
If the car next to you is receiving route data, they can open a spot for you to get to your exit.
The benefit is large and NOT REQUIRED for normal operation. It's the easiest coordination problem in the world, because it's all upside and practically atomic.

You could always give those cars their own section of the road like HOV lanes. EVs were granted access to HOV lanes in California as an incentive to increase EV adoption. A similar thing could happen with a dedicated autonomous lane that has a much higher speed limit.
