Speedtraps are hard to edit correctly on WME.
They don't snap properly, and a lot of times, they don't give a warning (when you're above the speed) because they're not snapped correctly.
Make them work like house numbers: with a direct link to the road.
Also, we could have the option to mark a speedtrap as "both ways" to reduce clutter on the navigation screen and speed up the work of Editors.
