Google Maps (or others) works good to find a resonable route, but I can do better on my own. One-way streets where bikes are allowed to go do opposite way is sometimes missing, short desire paths connecting bike ways, crossings where it's safe to do an (illegal) right-on-red etc.
Tried a GDPR data claim from Voi but got nothing back :( But I hope the data is somehow available for urban planners, think it would be a great source of truth to use in tools like this.
