EVs have heavier batteries and ICEs have heavier engines and drivetrains. Go compare two similar models at most brands and the curb weight will be within 50-100kg. Add in a full tank of gas to the ICE and the will likely weigh about the same.
I guess it's increased/comparable weight + lack of gas tax. There's definitely something thrown off by EVs and the suggestion to tax charging EVs specifically makes sense.
What about them? 10 years ago the best-selling vehicle in the US was a sedan. Today it's a pickup truck. Nobody said boo about road damage. It's a made-up reason to hate on EVs.
