Let’s stay with self-driving cats, could be the next hot YouTube meme ;-)

Good weekend to all,

Wrt super chatty self driving cars, aggregate bandwidth is the issue and there will be a lot of work carriers have to do to support cell density at scale. Having your car stop working in a cell dead zone seems like a bad consumer experience...
