I saw the video a few days ago. It uses some napkin math but the author does at least use a spreadsheet / toy model to arrive at their conclusions.

Ohhh okay ty "throwaway920102" will take your word for this.

Ray is a reasonably well-known current/former professional city planner who does look at data to make his content.

The videos he makes do sometimes use napkin math but in the way a city planner does napkin math - with data.

They also don’t claim to be a comprehensive study and each video is accompanied by a pretty thorough disclaimer on what methods are being used.

Odd and unfortunate that this one was taken down.

Was trying to be at least a little helpful "irl_zebra", not to suggest the video was sufficient evidence.
