This is true, but the problem is that there is so much low-hanging fruit here like painting new lines, adding cheap concrete barriers, or installing elevated crosswalks.
The price is far far less than whatever the price of a human life is. The reason they are not implemented is not cost, but because people here consider it their god-given right to drive as quickly and aggressively as they want.

Yep. A major arterial in my city is very obviously too wide for the traffic it carries, even during rush hour. I don't remember the exact number, but a study a few years ago found that the average speed was something like 12 MPH above the posted limit. People completely lost their shit when it was proposed to narrow it and put in bike lanes (the bike lanes weren't the point, but people were cycling on the sidewalk to avoid the impatient/distracted/aggressive drivers, and it would have been silly to not use the space for anything at all).
