The Highway Is a Pasture

Description and use

Longplay adapts music in real time using vehicle telemetry to reduce driver monotony and increase engagement, though safety benefits are unproven.

Problem

Drivers experience monotony on long highway trips, leading to attention drift and potential safety risks. The challenge is to keep drivers engaged without adding distraction.

Outcome

The system adapts music to driving context, potentially reducing driver stress in congestion and making long drives feel more engaging, though objective safety benefits remain unproven.

Workflow

• Read telemetry from Tesla Fleet API
• Compute pace, ETA, journey phase, and moments
• Generate deterministic musical brief
• Create candidate list at edge
• Score candidates with weighted factors (confidence, contextFit, telemetryFit, tasteFit, diversityGain, novelty, fatiguePenalty)
• Resolve tracks via Spotify API
• Append selected tracks to playback queue
• Repeat every few minutes

Evidence

When recent telemetry snapshots show increasing route delay and stop‑and‑go movement, deterministic rules change the musical brief.

Source

Preferred music may limit reported driver stress in highly congested traffic.

Source

Music can change the experience of fatigue without reliably changing the underlying impairment.
