Not sure if anyone else is experiencing it on 2016 MDX but wanted to share. Driver's side blind spot sensor goes crazy when you drive on the far left lane in the traffic separated by the concrete barrier... and if it's raining at the same time. I imagine areas of rain / humidity and close proximity to a traffic barrier are causing some false positives:

Rain is suppose to be some of the items that give you false positive for BSI along with (pg 406 of 16 MDX owner's manual):

• Objects (guard rails, poles, trees, etc,.) are detected.
• An object that does not reflect radio waves well, such as a motorcycle, is in the alert zone.
• Driving on a curved road.
• A vehicle is moving from a far lane to the adjacent lane.
• The system picks up external electrical interference.
• The rear bumper or the sensors have been improperly repaired or the rear bumper has been deformed.
• The orientation of the sensors has been changed.
• In bad weather (Heavy rain, snow, and fog).

Thanks for finding explanation in the manual, this is exactly it - a combination of two known factors! I'll treat it as a documented "side effect" then, nothing significant to worry about...
