I preferred the pool noodle with "I have coronavirus" painted on it version.
They could go to a bit more effort tho. That thing doesn't even have Bluetooth...
(To be briefly serious, I did at one point have reason to travel by bicycle carrying a long poster tube, and after a couple of attempts to bungee it to the toptube in a way that didn't interfere with pedalling, decided sod it and strapped it across the rear rack in that style. The effect was the sort of room you get when riding a recumbent trike, and - as I discovered slightly too late - similar issues with narrow gaps between bollards.)
