I synthetic fuels are a temporary solution for cars. If you are changing car infrastructure, IMO it makes most sense to switch over to electricity (highest efficiency and you can use electrical car batteries to stabilize the grid).

Synthetic fuels will make most sense for aviation (higher energy density compared to hydrogen), (possibly) shipping and as a transitional fuel for transport to reduce our emissions.

Synthetic fuels could also be a solution for seasonal storage.
