a switchback is several alternating curves in a road or pathway
mountanous areas such as Colorado or British Columbia have lots of them, its to make climbing short steep grades easier on vehicles.
when talking about "drifts" she was talking to about snow drifts..
which reduces visibility for obvious reasons and makes accidents worse due to limited spacing on each side of the road.
now picture snow drifts on a switchback and you'll know what she drives through.
I don't think you're uncultured, you've just never had to deal with it before.
Hope I explained it well enough ^_^

hard to tell how fast you could do, also depends on if you want to powerslide through all the corners, and if you're going down or up hill. I'd go faster up than down, but thats cause I don't like the thought of falling down. From the looks of them, I'd say.. 100-120kph for pure slides and really high g's, but otherwise 60-80kph. Where I lived in BC we had some really nice ones on gravel road, used to go round them about 60kph in my Rabbit sideways, loads of fun but cost me a set of tires.
