>> The construction of new paternosters is no longer allowed in many countries because of the high risk of accident for people who cannot use the lift properly. In 2012, an 81-year-old man was killed when he fell into the shaft of a paternoster in the Dutch city of The Hague. Elderly people, disabled people, and children are the most in danger of being crushed or losing a limb.
Generally if a country bans it due to safety, it could be pretty terrifying to use it.
Those things are absolutely amazing in busy buildings like universities. Where you have an extreme throughput in short intervals. I studied in a 15 story building and even with 4 big elevators you had to wait forever during rush time.
Here you can see one working in the Goethe University in Frankfurt. Sadly, now you need a "drivers license" to ride the damn thing and are only allowed to use it alone. https://youtu.be/zFikKlHHCbw?t=20
Ski lifts are more dangerous.
edit: used to* apparently after they were made fun of by extra3 they got rid of the paternoster police and drivers licenses.
