This depends on the country in context. There are countries e.g. Japan, some parts of Netherlands, that people do not bother having locks for their bicycles, scooters or motorbikes.
So nothing out of the ordinary here. The twisty lock' s purpose here would have been to prop up the bike AFAIK.
It is a curious fact that of all the illusions that beset mankind, none is quite as curious as that tendency to suppose that we are mentally and morally superior to those who differ from us in opinion.
