I see all the time on the Internet (and even IRL once) people make claims like, "oh, carbon taxes will just increase CO2 output, you know like in that Israeli daycare study." Drives me nuts.
Are fines the best possible solution to this particularly traffic problem? I have no idea. I'm not an expert in this area. But I am highly confident that whatever relation it has to the Haifa daycare study is so incredibly tenuous that it is not worth mentioning.
The reason I said anything in the first place is that I object to automatically administered punishment. Either separately can be OK. Automatically administered? No problem, that's called a tax (including use taxes like tolls). Punishment? Then we'd better have due process, and yeah, it's going to be expensive and labor-intensive to administer, but that's critical in a free country. That's why I called out the "is better than" quote. I think it's strictly worse.
