I suppose it depends on what the “greater good” is. If I was doing significant harm or likely to do significant harm in a way that could only be prevented by not driving (for example, if I was a dangerous driver due to some disability) then I would feel a moral obligation not to drive. If, however, I was simply causing a very small part of a much bigger problem (such a pollution) then I would be open to paying a tax or fee to compensate for the harm I was doing, but I would still drive. I think I contribute to society and therefore I do feel entitled to use a fair share of society’s resources. If I was merely offending the sensibilities of people who think that a society with fewer drivers is better in some unquantifiable moral or aesthetic way then I wouldn’t feel any obligation to cooperate with them.
