Let's also not forget that this issue applied to ICE vehicles as well for decades. The EPA city/highway MPG ratings were always way higher on paper than in practice until they reformulated their testing several years back to give more accurate numbers.

Do you have a source for the reformulation? I’m newer in industry and don’t remember a reformulation. I’d be interested to know more

EPA periodically updates its methodology to account for changes in vehicle technologies, driver behavior, and/or driving conditions. The 2008 changes were broad revisions to the entire methodology that lowered the fuel economy estimates for all vehicles. The updates for 2017 will reduce some fuel economy estimates by 1 mile per gallon (MPG) and a small number by 2 MPG.
