Here's my theory with some insight from lead marketing folks I got to chat with during filming.
CDM was originally intended to be MUCH bigger than it was. Probably on TV and not just YT. It was originally planned before COVID but got shut down during the height of the pandemic. During that delay Stellantis bought FCA out and took over and severely cut the CDM budget which was still huge based on what I saw. I had lunch with one of the lead marketing guys and he flat out told me it was originally planned to be way bigger than what I was seeing.
I think CDM was originally meant to promote the Redeye platform.
Then FJB took over, signed anything put in front of him, and basically cancelled Hellcats. Dodge went EV, they pivoted CDM to promote EVs to millennials, and went with the person they thought best fit that demographic.
That's my theory anyway.
