It would be good to tell clearly on the website that tourists cannot use your service - which requires BankID that is apparently connected to Norwegian bank account. It took annoyingly long to find out this - I installed the app etc.
I am afraid it is typically Norwegian to only offer one soiution for everybody and to not offer anything extra in terms of flexibilty and customer service

I lived in the same delusion, that I will use their service when I visit Oslo.
I downloaded the app and the bubble had burst when I saw no alternative registration only norvegian bank ID

Thank you for your feedback!
We will build a solution where tourists without Norwegian, Swedish or Danish national ID can book Hyre-cars during the autumn of 2025!
