They have "funny" thresholds....when I hit that 300 lb. buck on Christmas Eve 2019 dead-on at 55 MPH with my 2017 Ford Escape, the airbags did not deploy. BUT....the clutches in both front seatbelts were burned out and would not hold at all (my body shop guy showed me).
EDIT: This is what those seatbelts did (I'm on coumadin).
