Board Analysis
Opening, mid-game, and finishing states sampled from the video.
Inside-Out Oval
The road forms an oval, and the central columns are taller than they first appear. Yellow and blue are near the top entrance, green and cyan sit through the middle, and pink/purple columns wait lower down.
Open the oval with yellow from the top, then blue from the upper entrance. Once the entrance is usable, work the green center column. Continue with cyan through the center, keeping the oval from holding stray lower cars.
Only after the middle has lost height should you release pink and purple from the lower columns. Finish with the remaining orange/yellow side cars.
Order:
yellow top entrance -> blue upper entrance -> green center column -> cyan center -> pink/purple lower columns -> orange/yellow side cleanup
The oval is a road, not a spare container. Lower colors are much safer after green and cyan have opened the center.
