At the moment, we identify two very different track elements with the term corkscrew.
Corkscrew l/r
and
Corkscrew u/d
For the first use it is a very good name because it is a stunt and in other fields (airplane acrobatics or rollercoasters) the same term is used
For the latter, I don't think it suits the track element very well.
It is a more normal road element that exists in real life. Its shape is a helix (a corkscrew technically as well, but that is not the point).
I think the term helix would fit better. You can also more easily clarify what type orientated from driving direction, like; Down left or up left. Down right or Up right,
In the attached image, I used a chicane /L with a helix u/l and a helix d/r ..
I think it helps in describing things.
If we ever create a track element that lets you ride the wall up or down, then the corkscrew would be appropriate again

Any opinions?
