At Bohinj municipality I inquired about parking at Savica. This is what they told me:
- Parking lot is private property, owner (allegedly Metropolitana, owned by Ljubljana archdiocese), charges 10€ per day, even in winter.
- Collector should be there every day 6 to 22, but in practice not always. If bad luck he's there, you pay for that day
- Municipality has nothing to do with it, except posted parking info on their site. That means no fine if you park there and no collector to charge you
- But careful to park in the lot. If on road before, easy prey for municipal warden.
Good we don't need ticket for path to Komna.
