In order to comply with Getaround's insurance conditions, for a classical rental, you need to present to the owner at check-in:
Your original driving license (no copy or theft / loss statement)
The credit card under your first name and last name used for the payment of the rental
Secondary drivers will also have to present their driving license to the owner to be added to the rental agreement and benefit from the insurance coverage.
For a Getaround Connect rental, you'll need to make sure your driving license was validated by Getaround before the beginning of the rental.
