I asked a LR service tech the same question when I purchased my '11 LR4 HSE. I got pretty much the exact same response that @jaguardoc504 just shared.
Somewhat surprisingly, adjusting to the lack of passive entry/start was probably the biggest part of settling into the LR4 vs my previous vehicle (a '11 American sedan). That and lack of BT audio streaming. And adaptive cruise control. And blind spot monitoring. And auto-dimming high beams. And ventilated seats. But I'm not judging! I love my LR4 for different reasons!
