Does this mean diagonally? What's the distance to "adjacent"? One city block? Two? Does this mean that jaywalking is still practically illegal in most dense cities/downtown areas?

The lack of clarity is pretty frustrating with many of these laws. I understand the practical need for wiggle room, but this almost seems like a trap! My naive interpretation is that police will still have plenty of opportunity to use jaywalking in the ways that the law was trying to prevent, especially in densely populated areas.

I used to live on a street where crossing it legally meant a one mile trek, so it's appreciated, especially since I was warned once, but I now have no idea if it would be legal or not, since there was a light half mile in either direction.

Also, there's not that many adjacent controlled intersections. Driveways are intersections, too, and are rarely controlled.
