remove implication hummer -> motor_vehicle
The edits are too old to see the exact wiki text, but I believe the Hummer tag used to be used as if it was a type of vehicle, when Hummer is in fact a brand. The term Hummer is not used as a generic term for a style of vehicle like jeep is (that's a whole other can of worms to deal with since it's both used as a generic term and a specific brand), and we don't implicate other manufacturers to motor vehicle since there could easily be a post featuring just the logo as a sponsor, a toy version of their vehicle, or a sci-fi/fantasy design based on the brand. The military version already has a separate dedicated tag under Humvee, the term Hummer is just the name of the civilian brand and its models.
