It should be a free service anyway. Without free public transport, democracy does not exists. Same reason healthcare and education should be. So sure, you are “stealing” a ride - something that should be yours anyway because people are not born with the ability to travel kilometers of cityscapes, something that is now mandatory to survive and thrive.
