Australian Car Repair Issues? Ask an Auto Mechanic for Answers ASAP
Any collision avoidance system uses a combination of radar and/or camera inputs to determine size and distance of objects. Some objects may not present well to the system. They are designed to see a normal vehicle within a set of parameters.
The system is a supplementary safety system, and so would only normally take over in the advent the driver is unaware of a pending collision.
I would not trust any vehicle system like this as the primary.
The driver is always the primary.
Hope this helps.
