Which Crypto will be able to get Autonomous cars talking to each other?

Good Morning Crypto world! I have a question for the future about self driving cars and cryptos influence on the technology. If EVs and self driving technologies really start to take off, there will have to be some technology providing not only security, but also coordination between all vehicles (cars, delivery vans, semis) to efficiently and safely get from point A to B. I believe the paradigm shift is happening as we speak. The more autonomous cars on the road, the more need for coordination and security.

Which blockchain/crypto could supply both? If blockchain is really just "truth" then it makes sense to me that it could be used to prevent hackers from hi-jacking my self driving Uber. Because let's face it mean people suck and it would be a bad day if someone decided to make my taxi go over a cliff. Blockchain could stop someone trying to hack into my route and kick it out of the consensus as bull s**t. It would also work for talking from one taxi to the next in a line of taxis.

Additionally, let's say I am late for a date and want to jump the line. Crypto could be a way to pay all the other taxis on the road for the inconvenience to everyone else to go faster.

Let's really figure out all the possibilities for blockchain and who is already working on it? Time to make some real money…not fiat!
