Another woman working on the streets in Canada said she was no longer able to talk through the car window to ensure they felt safe.
But why? Why did she feel she couldn't stay outside? Is there more context?
The weather being cold is not a consequence of Nordic Model, you can't lower temperatures by using words like "Nordic". Canada has always been cold.
And she wouldn't have been harrassed by police, as Nordic Model doesn't involve criminalising prostituted women.
So the only thing I can imagine to be the reason for this is that she thought she had to get into the car immediately or the punter would have felt unsafe and driven away.
Nordic Model should be - and is, in the original model - accompanied by fighting poverty.
So, ideally, a prostituted woman shouldn't feel that anxious about losing one punter. It should even be possible for her to only engage in prostitution when the weather is warm enough.
It is quite likely that Nordic Model isn't implemented properly - I have read about problems in Sweden, like policemen being all too willing to send letters to the work address of a punter so his wife wouldn't find out ...
But that's not a problem with the model, it is a problem with the implementation.
Policemen who harrass prostituted women despite being clearly told that this is not their job (anymore) would occur in legalised prostitution, too.
