Rain fade affects GPS does it not? Is the car relying on inertial navigation for a period? This rain is not something a camera and iffy GPS signal can keep you on the road. The intensity and amount of rain would definitely not let a camera see. Quick add: this was at 12PM (noon) on a countryish road. City lights had nothing to do here.
