There's a road near the University of Waterloo where students get hit, some killed, on pretty much an annual basis. Often it boils down to the large number of foreign students who come from a part of the world where for one reason or another, you just don't need to bother looking before crossing, so they don't and walk right in front of cars (and in one case a city bus).

To me this is an example of the overwhelming importance of locale-specific context. When I'm near UW, my driving behaviour changes significantly even though the laws do not.
