Previous cars + blockchain either put sensor data on-chain, or collect GPS data, or trace supply chains, etc. As the computing power of new energy vehicles increases, there are more and more high-computing-power cars on the road. This increased computing power provides computational support for intelligent driving. Each car is an ideal decentralized node. Is there a public chain design with a light node mechanism that doesn't care too much about whether nodes are online 24 hours a day, allowing each high-computing-power car to run as a validator! Charging electric cars is not expensive, and the incentives don't need to be too high, but there are always cars online on the road. Perhaps there will be significantly fewer online at night, but it can cover more time zones and can have incentives similar to the peaks and valleys of the power grid. The more challenging aspects may be access and regional security restrictions. Just brainstorming without starting a business.
