On extra moving turns, the simple rule still wins

Lab research, not a vehicle function. advisory_not_promoted. Named license: obstacle zips 0006–0009, test-only. This page is the expanded moving-turning stratum, not a new Gate A. Frozen 0.620 / 0.922 stay on the cards — they are not repeated as a table here.

The 3-second question

We can see the last two seconds of another vehicle — a line of positions, in metres, relative to us. The job is to guess the next three seconds. Every scene here is a labelled turn at least 3 m/s.

The simple rule versus the neural network

The simple rule copies the last speed in a straight line. The network is the existing GRU (one fit, 12 of 40 epochs). Play draws the next three seconds on the browser clock. Pause freezes mid-draw. 1 / 2 / 3 seconds holds a finished frame.

Expanded moving-turning, not the parked-car hour

Not a second fit

Chunk 0006 clips were never train. The checkpoint and the 0005 train standardizer are unchanged. This page does not issue Gate A PASS or FAIL.

Not a brake, not a steer, not a command. advisory_not_promoted. License cap: 0006–0009; we stopped after 0006. Neighbors and extra seconds — one later experiment; still lost. 2 s heading and neighbor coasts — measurement, not a map grant. History-only tree vs the simple rule — milder arcs; not Gate A. Frozen 0.620 / 0.922 stay on the cards.
