So sad, when driving, man must be in his cocoon, minding his own Business, must not be offended by other mothballed irritants, so that THEMS that be needed to save a life, must boost the audio and visual fireworks to get some space to get life saving equipment to save another of homo erectus.[Sapiens - no, not wise just upright,sumtimes ] PS. Every car should have a receiver of an emergency infra red signal that when activated by a rushing Rescue team, will activate the cell phone, radio ,cd player or video warning display under the rear view mirror, and tell the driver of said vehicle to move over , thereby reducing the need to have brain shattering 105 decibels of hee haws, as there so many that have a restriction already in the ear duct from brain shattering music, can not hear a Jet plane taking off. Here in La La Land, many Traffick lights have a receiver for an emegency signal that sets the lights in an appropiate mode to stop traffic from crossing the pathway of the Emergency vehicle, and keep the Green going so that the impediments in front of the vehicle can scoot out ot the way before being flattened. From a walking mover it appears to cut down on the number of ear shattering moments. When driving one has no idea, whence the audio be coming from when thee hear it, it could be just yards away in a blind spot on the side street., when that 100 plus decibel penitrates the thick glass and activates the sensors in the grey cells.
