Hi,

When the crossing is in a curve, I do it the way you describe, placing a
node at intersection. But when two straight ways (whatever the kind of way)
intersect, I prefer tracing the first line without intersection; then when
I trace the second one I reach the first line, and it helps at putting
that point more precisely.

You may find it useful when many lines are parallel. Example: when tracing
parking aisles, for the whole not to appear too messy at the end, you'd
rather first trace ways in one direction, then in the other, thus creating
intersections.

I also use this technique when I have to align some POI on parallel ways,
using a temporary way (virtual line that I then delete). Example: placing
lift gates on parallel ways for entering or exiting a parking, or a
motorway...
