A new study conducted by AAA shows rain actually impedes certain driver-assisted features.
In a study with rain patterns hitting a vehicle’s windshield, 33% of the time the cameras put into the car to assist did not see a vehicle in front of it, failing to deploy emergency brakes. This was done at 35 mph.
The cameras also failed to help with lane-keeping assistance.
The test has not been done with snowy conditions, but AAA warns people to not use cruise control in rain or snow.
Traction is important to be able to feel if the car is moving and cruise control takes that away.
