Unless you are taking part in quarter-mile drag-strip racing, I don't see the point of ever using LC on the road. The GTI is plenty fast enough on take-off, especially with a remap.
So, to answer the OP - Yes, the DSG can be driven as a full automatic and insurers class DSG as an Automatic. It's a new kind of 'automatic' though, and can be driven 'manually' as well.
