Ed Garsten just published a good Forbes.com article on the only topic (bizarrely) over which I have ever really seen self-driving car engineers get really angry at each other: DSRC (“mesh”) versus cellular networks for vehicle-to-vehicle communication.
“Score a big one for C-V2X which had previously won over Ford, which said in 2019 it would start installing the technology in its vehicles during calendar year 2022. But in Europe, Volkswagen AG, the world’s largest automaker, is already building DSRC-equipped vehicles setting the tone for the rest of the continent. In China, the world’s biggest automotive market, automakers have sided with C-V2X.
I am always amazed at how passionate engineers in this space are about this question. Still unsettled!
