Driving cars can be seen as a bad habit too. We could cut down on emissions a lot (in N. America anyways) if we committed to better public transport, cycling etc. There are some parallels between the tobacco and auto/petro industry. Many north american cities had excellent tram systems, but they were torn out/abandoned for car roads under pressure from industry lobbyists in the 50-70s. Some cities retained their tram lines (Portland, Toronto) from that era, but many did not (Chicago, Vancouver).
