Jaywalking is the one of the most absurd laws in the history of the entire world.
In the UK
pedestrians in the process of crossing at (unmarked) road junctions should have priority, as a matter of common curtesy
I love being English.
Common courtesy, and common sense, both lacking in most of the U.S., though not everywhere - in some States/cities it's like the U.K. sensibility.
Where I live, though, in New York State, people are so untrusting of cars (as they should be), they often won't cross
even if the driver halts and waves them out. Because you can get run down, and the driver gets off scott-free in many cases.
In NYC though, there is a lot more lemming-power, which helps halt the cars that would just as soon turn you into road pizza.
