In the UK, there are no laws against jaywalking. Motorists have to give priority to more vulnerable road users and you're required to be alert to risks and hazards. You would fail your test if you're inattentive and ignorant to the potential of pedestrians stepping into the road without checking properly.
If you go to a gun range and someone is between you and your target, are you expected to carry on shooting or be alert and aware of risks and capable of holding fire?
Hang on let me get my freedom fries, this is starting to get interesting.
There are also no laws against jaywalking in Australia, but there are laws that govern how people and traffic should interact, and running people over isn't a valid way to get to your destination, in fact even if it's seemingly entirely the pedestrian's fault, they walked out into traffic with headphones on, you can end up in serious trouble. If there are pedestrians around then you need to adjust your driving habits to take into account the pedestrians.
