People come to your city to do business there. If a lot of people do business in your city, a lot of people will be coming in and out of town every day. Complaining that the people who come to your city to do business (spend their money) are poluting a bit with their cars while they are there, and the cost of that pollution is unfairly borne by city dwellers I think is bizarre, because the benefits of those people coming into the city and spending all that money (which generates jobs and tax revenue, etc.) accrues to the city. The city is already being paid a very hefty return on the cost of cleaning up the pollution of people traveling into the city every day. The city would not want to discourage people from making the trip! Maybe more succinctly, the polluter is already paying the city more than enough to cover the cost of cleaning up the car pollution, by nature of the money they are spending while they are in the city.
