Car Sort: Color Puzzle Level 154 Solution Walkthrough
Board Analysis
Opening, mid-game, and finishing states sampled from the video.

Replay-Friendly Route
Level 154 has another wide S-road, but the replay frames make the correct priority easier to see. Blue and cyan sit on the upper and middle road sections. Yellow, green, pink, and purple are concentrated in the lower columns.
Begin with the road itself: clear blue from the upper road, then cyan from the middle bend. This keeps the S-shape from becoming a storage lane. Next remove the red/purple blockers near the bend, because they are what prevent lower columns from moving directly.
After the bend is open, pull yellow from the lower columns, then green. Finish by taking pink and purple from the bottom.
Route:
blue upper road -> cyan middle bend -> red/purple bend blockers -> yellow lower columns -> green lower columns -> pink/purple bottom
Do not use the lower columns as temporary parking. The video succeeds because the road is cleared before those columns start moving.
