Interesting that the limit is different for electric vehicles. I guess they tend to be heavier so it's sort of unavoidable, but it does potentially set up an imbalance that will need to be corrected at some point in the future. Of course, for now it's more important to convert as many vehicles to EVs as possible.
Not knowing how they get taxes for their roadways there, but in many places it's from fuel taxes which obviously EVs don't pay, and they're heavier too so even harder on the roads so the tax structure will need some rethinking whenever that tipping point is reached. Hopefully it's done in a way that doesn't eliminate the cost benefits of running an EV.
Batteries are heavy, while weight is a major contributor to road damage (and therefore societal cost) I believe it is more than offset by the reduction in emissions.
The difference in weight limit helps insure electric sedans aren't ruled out due to battery weight alone.
The law specifically causes the imbalance right now though, so now I'm extra confused. It's not some predicted possible future, it's about as immediate and direct as it gets. They've accounted for the fact the same vehicle as an EV is heavier, which is probably the best way to do this sort of thing as you don't want to discourage people from switching to greener options. I was pointing out the imbalance and then speculating on what it might mean in the future.
An extra tax on energy would be one way to do it, although I would personally prefer something directly tied to driving so that people are encouraged to use alternatives when they can.
Still a weird thing to do. My SUV, according to the internet, weighs between 1.63 and 1.70 metric tonnes (3,603 to 3,755 lbs). A sedan from the same brand and trim level weighs between 1.67 and 1.73 metric tonnes (3,676 to 3,816 lbs). Granted, sedans in the US are larger than what are sold in Europe, so they probably used cars sold there to come up with the weights.
