My Volkswagen has assistance features which routinely fail on snowy days and can’t seem to be disabled. The best you can do is disable them for a minute (!) at which point they start blaring again. Its ironic because the time you need the most focus is the time the car lets you focus the least.
BMW has the same issue but luckily still buttons to disable them. Snow will quickly result in "Forward collision warning failure" and "Blind spot detection failure" and if more snow "Lane assist failure" because the sensors get covered in snow.
Oh and before you even start driving let us "bing!" you with a message that the temperature is below 4C. As if you didn't know that already.
