Since 1961 this type of turnstile has been used at the USSR subway stations
I posted the first video I found. This one is broken but it shows how it works.
This type of turnstiles worked well but it was dangerous and a bit scary )

I like this approach where life safety codes make it difficult to put in a traditional turnstile

Eagerly looking forward to their Yosemite Sam trapdoor variant!

Am I the only one who likes the potential in this approach? I have run into projects that life safety codes prohibited anything other than an optical approach rather than physical - this would probably work in that application.

The turnstiles in the dflow videos I saw look like they are meant to keep people from entering unauthorized and allow free egress - they aren't even deployed until approached without authorization- wonder if you even need to deal with an override in this setup.
