《一段双车道公路》

《一段双车道公路》 is one of the major Sarah Pinsker / 莎拉·平斯克 stories discussed in 166.悠游长风：温柔的幻想之歌，抚平焦虑的沟壑. In the episode’s account, Andy loses an arm in a farming accident, receives a brain-computer-interface prosthetic, and begins to experience the arm as a specific two-lane road in eastern Colorado.

The story is useful to the wiki because it makes Embodied Identity Boundary / 身体身份边界 concrete. Andy’s attachment is not only to a device, a lost limb, an old lover’s tattoo, or a hallucinated place; it becomes an unnamed bond among body, chip, landscape, memory, and self-recognition. The episode reads the ending, where Susan converts the old Laurie tattoo into “科罗拉多”, as a memorial to an experience that cannot fit inside ordinary relationship labels.

Connections

• Sarah Pinsker / 莎拉·平斯克 and 《悠游长风》 / 《悠悠长风》 - author and collection.
• Embodied Identity Boundary / 身体身份边界, Embodied Personhood, and Robot-Human Boundary - main body/personhood frames.
• Gentle Speculative Ambiguity / 温柔的科幻暧昧 and Science Fiction Realism - why the road premise works as emotional realism rather than puzzle mechanics alone.
