I think he thought he could be competitive at Le Mans and would get a Toyota Hypercar seat but that plan didn't work out so now he's having fun in rally. Not sure that he wants to do a full season, maybe even he isn't sure. In his career he complained a lot about being first on the road, remember that for a while he had to do 2 days as first on the road so maybe now he is getting "revenge" for that doing his favourite rallies from a good start position.
