If you look at autofatalities (including of pedestrians and cyclists), share of public transit and bike usage, and other such related statistics over time, they closely track the cost of gas. Ironically, of course, production of new cars doesn't neccessarily mean less car usage over the <10 year term (since cars don't magically burn up), but it may mean good news for those who want to wean their cities off of cars.
