As a kid in the 90’s sitting in the back of the car in a long traffic jam I’d always think of those toy cars that followed an inductive ink path. My kid brain thought “wouldn’t it be cool if when the light turned green some of that ink bubbled up and all the cars started going at once instead of one after another” Anyway - as self driving cars have gotten closer and closer to real, I always assumed eventually when most all cars were self driving, there’d be some standardized protocol for cars to coordinate with one another. It’s hilariously depressing that cars in the same fleet have no interexchange.
