I think it’s probably likely that EVs are inherently a little heavier than ICEs, but I don’t think it explains all of the weight growth trend of EVs. If we want to make sure that EVs do not become uncompetitive in relation to ICEs under this type of scheme, you could simply give them the first N kilograms off. This makes sure that the property of road wear still gets priced in for relatively heavier EVs, without making them directly uncompetitive.
