I work with electric utilities, and every time we talk with car manufacturers (including recently Tesla) they say vehicle-to-grid (v2g) isn't on the roadmap. On the other hand, almost all charging happens at night, which is a time of low demand on the grid. And delayed charging (combined with time-of-use rates) to move off of the 7 PM winter peaks is widely available. So even without v2g, vehicle electrification has worked out great on the grid so far.

Governments generally run electricity grids though. If V2G is wanted, it could simply be mandated.

It's definitely on the roadmap in Europe: https://www.greencarcongress.com/2019/03/groupe-renault-launching-large-scale-v2g-trials-with-fleet-of-15-zoe-evs.html https://www.greencarcongress.com/2019/03/groupe-renault-laun...

I worked on a software design project a year or two ago that was exploring the user interface and incentive mechanisms for the consumer side of such a scheme. This was for one of the big-3 German automakers and the company running a significant portion of Europe's energy grid. It's still a while off, but it is a serious project with the intend to get to market. I'm no expert on the grid side, but if I'm not mistaken, the need just isn't quite there yet because the grid have been able to accommodate current renewable production levels.
