[SM] Looking at the wikipedia article on slicing I see:
"Network slicing emerges as an essential technique in 5G networks to accommodate such different and possibly contrasting quality of service (QoS) requirements exploiting a single physical network infrastructure.[1][13]
[...]
Impact and applications
In commercial terms, network slicing allows a mobile operator to create specific virtual networks that cater to particular clients and use cases. Certain applications - such as mobile broadband, machine-to-machine communications (e.g. in manufacturing or logistics), or smart cars - will benefit from leveraging different aspects of 5G technology. One might require higher speeds, another low latency, and yet another access to edge computingresources. By creating separate slices that prioritise specific resources a 5G operator can offer tailored solutions to particular industries.[14][15]: 3  Some sources insist this will revolutionise industries like marketing, augmented reality, or mobile gaming,[16][17] while others are more cautious, pointing to unevenness in network coverage and poor reach of advantages beyond increased speed.[18][19]"

As expected this technique is designed to allow exactly what NN was designed to prohibit (treating packets differentially in the internet based on economic considerations*)... this is IMHO why instead of calling a spade a spade mobile carriers avoid describing this in a useful way, as it is exactly about prioritisation... IMHO that will back fire, and a better avenue would be to be open about what it enables and propose a method to restrict the potential issues. E.g. (I am making this up on the fly, so it will likely not hold up to any degree of scrutiny) by self limiting to never commit more than X% of a cell's capacity to slicing, IFF the cell is used for normal end user service at all. So admit that there is some trade-off here, limit the fall-out, and then describe why we as a society should embrace that trade-off. I am a bit sceptical about the whole car 2 car communication thing (that is cars talk to cars, not people n cars talk to people on cars ;) ), but if a Carrier believes there is value in that for e.g. accident avoidance, then tell how this requires the stricter network guarantees that (only?) slicing can deliver.

Personally I still think this is not an attractive proposition, but I am not the audience for that anyway; the relevant regulatory agency and the legislative is.

*) This is a (too) short condensation of the rationale of the EU for stepping into the NN debate.
