Come to think about it, we might need some cost analysis for this bill. While we wait for official GM numbers, I'll do the laziest analysis ever to get a rough reference
III.7 doesn't apply until 2020 so the cost there is 0 this year.
III.6: According to
this article, 350 000 electric vehicles will be sold in the US in 2020. However most seem to be in California (which alone has 46% marketshare!). Still, let's assume new sales are divided equally among all 3 regions to be safe. That means 116667 electric vehicles sold in Lincoln. We'll round that up to 125 000.
According to
this other article Illinois proposed a 1000$ registration fee for electric vehicles but this seems an exception and a weird hike. The old price was $17.50, so let's take the sensible number instead.
This all adds up to $2 041 667 in extra costs. So overall small. Take this estimate with a huge grain of salt, but it's something we might be able to ignore or will add up to like 0.01bn at worst.
III.4: This one would actually require a lot more complicated analysis. So instead I'll just get around by lazily designing a loophole. Let's just say the toll operators will be required to handle the lost revenue by themselves.
I imagine overall this requires
some sort of increase to the transportation budget in order to indirectly fund this though.
The rest of the bill doesn't require any cost analysis.
