Thank you for acknowledging this and letting others know about the massive undertaking that is "implementing Sentry Mode". Yes, the Air has cameras, and effectively
none of the other elements that are required to provide a customer with a fully-functional, park-and-forget, sensitivity-adjustable, remotely-viewable, BMS-compatible, geo-fenced, 24/7, 360° surveillance system.
As for Hands-Free Drive Assist, I only hope that the Air's ADAS has seen a massive improvement over the arguably dangerous
Out of Spec showcase from six months ago. After seeing that video and reading several posts concerning "phantom braking", I haven't touched Drive Assist. Thankfully, I'd rather be the one driving the Air 99% of the time anyway.
