If it's not impressive it's because a certain player in the field has distorted the standards of rigor for self driving for so many people with "Autopilot".
The fact you watch a video while it's active is a tiny difference to the driver (especially since some people are already watching videos using LKA), but a HUGE difference in terms of what the system is doing. The fact the system is driving with full responsibility on Honda
To the point that instead of seeing existing LKA as a step behind this, you might as well see them as existing on different planes, where progress towards A does not affect progress towards B meaningfully
