Delivery robots didn’t get approved overnight, they were being introduced and control tested as far back as 2015 in cities near me. Delivery robots also stand to make a profit for someone, so there was incentive to get them on measures and in front of legislation. Unless the unicycle manufacturers are petitioning to get them approved (unlikely since they make no money past the point of sale), it’s unlikely anyone has actually pushed them gotten them added to a measure and started the legislative review process.
Regardless though, I’m citing the article, which most people - you included id wager - didn’t actually read (which is totally fair, I don’t usually either but there weren’t comments yet!). So call bullshit on them!
