Neither the Youtube title "Adam Savage's Spot Robot Rickshaw Carriage!" or current HN title "Adam Savage Builds a Rickshaw Pulled by Boston Dynamic's Spot Robot" are clickbait.
Both are reasonable.
The only issue with the Youtube channel title might be the "!", it is a little clickbaity that I would agree seems more the work of a PR team.
The problem with the video is -
The rickshaw doesn't look great.
At the end of the day it's just a "I built a rickshaw" video.
But, people would pay money to use a spot rickshaw and it looks potentially awesome. Adam even talks about the 'visual experience'.
He was trying for a visual experience and I personally think he failed. But he came close. Maybe your issue is it was a kinda fail video, which are good to have, but they present it as a ! success?
Spots's are said to be the price of a luxury car whatever that means, seems like you need multiple. I don't think it'd work outside of a loss leader for someone like Disney atm.
