I would have loved to subscribe to the Official F1 calendar and have it update live, though this level of permission is way too much.
There are other sites that allow you to download a .ics file to populate the calendar app of your choice, obviously with no data collection.
Only trouble is, if an event gets rescheduled, the event won't be updated on your calendar.
Instead of importing the ics, you can use a webcal subscription link, like f1calendar provides. Still no permissions or data collection, but it will update the events as changes occur
