Hum... Announcing you will completely outlaw combustion cars soon is missing from the GP's options.

AFAICT, that increases sales. "I better buy it now, it's going to be banned soon". Just ask the American gun manufacturers. They love announcements of bans because it provides a huge immediate boost in sales. And then in the end the ban ends up being watered down/removed, just like the European bans of combustion vehicles have been.
