There is a known "flaw" with all these systems. Essentially most are based on a optical sensor the full width of the front bumper area.
If the loads involved are significant enough or a simple bump compression in the right area then it will set off. The rams are one use items as well. |

Well I guess the cause was the Mrs hitting the speed bump too fast, the lower bumper bottomed out on the ramp as can be revealed by some lights scrapes underneath, this was enough to trigger the safety system.
Expensive lesson learned. |
