Tax SUVs out of existence.

A basic BMW 5 series is over 2 tonnes, with the top spec model tipping the scales at 2.5 tonnes. I mean I agree with the general sentiment but it's not just SUVs that need to go on a diet. Everything is getting heavier and heavier and heavier.

yeah, the tax should be based on car weight per passanger

That will just make the gigantic SUVs with 7 or more seats dominate even more.

car weight / min(number of seats, number of people in the family)

This metric disincentivizes carpooling -- everyone should drive a light single-seater to minimize their tax.

(I agree with the spirit, just calling out that there are going to be edge cases galore with a scenario like this)

Do people car pool anymore?

I see the same trend. My thoughts: 2 tonnes of shit sells for more than 1 tonne of shit. 650 HP entices a lot more people than 1,200kg. I usually have to dig to find the weight of the vehicle. It's a consumer education problem more than anything imo.

In Mazda we trust! Apparently they'll try to make the NE under a ton.

Ironically, they've been taxed into existence.

Not really. Small cars are still on sale in US. SUVs are popular in EU as well.
