Are you sure the tunnel geometry changes are correct?

1. Is aerial imagery the only source? This is on a hillside, so the accuracy wouldn't be great.
2. Other aerial imageries seem to disagree with the new geometry.
3. From my east-bound bus-taking experiences for TKO tunnel, exiting the bus interchange and into the tunnel is almost straight, while other vehicles have to bend slightly left to align with the tunnel approach, before turning slightly right again immediately after entering the tunnel, which seems to correlate with the old geometry better.
4. Under the new geometry, the west-bound tunnel turns slight left before exiting, then turns right again. I find this road design rather unbelievable, and while the former western tunnel approach has seen a lot of works after the demolition of the toll plaza, it can't possibly change the tunnel alignment, right? (Is it even possible to move a tunnel? If not, then the tunnel geometry should be the exact same as the original plan in the 1980s, and I don't think a sensible planner would make such curves.)

As such, I highly doubt the accuracy of the "calibration" and "beautification" of the path shapes here, and I would suggest using other tools to verify the alignment. See also another reverted dubious hilly calibration: https://www.openstreetmap.org/changeset/168519808
