If you don't work IT, retail, or food service what do you do for work?
Sometimes on Lemmy these seem like the only jobs that actually exist, but I'm sure there's a lot of people here with different and unusual lines of work.
Interesting thought, I did do some work with DSRC systems for Vehicle-to-Vehicle communication, but DSRC is still pretty rare. Back during Obama's presidency the OEMs seemed to just be exploring a bit and waiting to see if it became a mandated safety system, but that never materialized.
These days the market seems to be moving towards Cellular Vehicle to Vehicle on 5G ( peer-to-peer), but once these techs have more adoption I think it's more likely that the car would connect to a dedicated piece of infrastructure that would relay with the cloud. Despite there being movement towards having more computing power in vehicle, I.M.O. the OEMS are too conservative on spending for computing power, so I don't see a future where the cloud is other cars. If cars still exist in 20 years, I would be amazed if vehicle networks weren't ubiquitous for safety though.
