All these high-end sensors will need to be disabled when driving in many bad weather conditions or bad driving conditions. i.e. off-roading, snowing, etc.
This is the same situation in practically all vehicles with these high-end features.
Even the ABS, etc brakes may fail if you are off-roading and certain type of mud/rocks/debree gets in between the sensors.
When in deep snow, sand, mud, etc. you should turn off the stability control to avoid the computer to cut off engine power to the wheels.
The collision options should only be used on highways/roads and on normal conditions and not in extreme conditions. It is radar based so it is obvious that anything that obstructs the radar waves will affect this feature.
In some SUV's with low range options (for mud, snow, sand, ice, etc) the disabling or tuning off of these features is done automatically since the low range is designed for off-road conditions and the vehicle will know it does not want certain features on or at full sensitivity. In our case, we don't have low-range features, so we have to do this manually. There is no easy way for sensors and computers to determine the weather and road types so it relies on the driver to turn on/off certain features.
I don't think anybody will expect radar based features, stability control features, cameras, etc. to work in all muddy, ice/snow, and extreme weather conditions. Some of these features work like the rear view camera or even the HID lights, you will need to clean the sensors/devices-IO areas so that they can receive/emit the proper information and process the information correctly.
