Answer: b.)the seeing impaired may have more difficulty when crossing the street

When a person's vision is impaired, the other senses become more acute as they try to compensate the lack of vision. Thus, such persons rely heavily on hearing when navigating complex environments such as a city.

Due to the high amount of ambient noise specific to a metropolitan area, hybrid cars will me much more difficult to detect as they are more silent than their gasoline-powered counterparts.

Furthermore, a person with an impaired vision, may have never heard before the sound an hybrid car makes. Thus, even though they may hear the noise, they may fail to recognize it as a moving vehicle. Generally, the brain must go through a period of learning in which a specific sound is associated with a specific phenomenon or object. Hybrid cars as well as electric cars that are even more silent, may pose an unexpected danger to visually impaired persons.
