Tesla's AEB likely triggers earlier than many others. See this example http://youtu.be/FadR7ETT_1k http://youtu.be/FadR7ETT_1k . The vehicles ahead were moving, but after http://www.tesla.com/blog/upgrading-autopilot-seeing-world-radar http://www.tesla.com/blog/upgrading-autopilot-seeing-world-r... was implemented in software 8.0, I believe the same was possible for already-stopped vehicles, too. We'll find out in the accident report, and perhaps directly from Tesla after they retrieve the vehicle's data.
