I've written a couple of times on the consequences our transportation choices have on people far away from us. In this Streetfilms interview, ethicist Randy Cohen brings it home to the local level.
Cohen tells us that ethics concerns itself with the effects of our actions on other people. Very few people think of the impact we make when we make a decision (or, more often, no intentional decision) on our mode of transportation. Cohen discusses the issues surrounding individual freedoms versus the public costs in the video interview. Watch it here.
