You wouldn’t believe the secondary costs caused by thawing salt. And then there’s the primary cost of operating vehicle park to spread a lot of salt each winter.

Although general streets would not be my first choice (you should start with bridges where corrosion is even more of an issue) every example of heated street I saw was just a matter of “yeah, simple math says this makes sense”.

PS: And that’s obviously not car-specific even. Every newly build bike lane should incorporate this idea. Modern bike and pedestrian bridges doubly so.

PPS: For reference: new bicycle-bridge in Germany… 16 million € to build, of which the added heating is a very small fraction (300k).

Requirements: hardware (optional)

it’s centrists and progressives who arguably have more money who are buying these cars

What are they to buy alternatively? The basically non-existent sanely sized cars?
