Getting a car to drive forward between the [[white]] and [[yellow]] lines of a road is not as difficult as one might think.  Sensors and [[computer]]s have advanced to the point that understanding the surroundings, and reacting to them is entirely feasible.  Even fine-tuned maneuvering can be performed by modern [[technology]].  The truly complicated part of development is detecting and responding to the unexpected.  Poor driving conditions can be an issue as well as road construction, but the erratic driving of others is probably the most serious concern.  Those driving under the influence of [[alcohol]] can be particularly as issue, since the computer will have a hard time trying to predict what will happen next.<br />

An overlying problem is that experienced human drivers have a certain situational awareness.  They know what to expect and prepare for, while the computer driver operates almost entirely from a "snapshot" view.  While a human might see a red street light through the trees and begin to slow, the [[computer]] will not recognize it until the light is closer.  Likewise for many other situations, like a pedestrian crossing the street or brake light coming on up ahead.  A human knows what will happen next from experience, but the computer can only try to guess from records and guidelines.<ref name="bbc.com">http://www.bbc.com/future/story/20150824-what-may-be-self-driving-cars-biggest-problem</ref><br />

Another consideration is that if autonomous cars become common, what kind of driving skill with future drivers have?  At a critical moment when the car tells them to take control, will they be capable of solving the problem?  Also, what will the focus of the "psudo-driver" be?  If an experienced driver was watching the road as if they were driving, they could probably react to a situation effectively.  However, if "nothing ever goes wrong" so they get distracted with a [[Cellular phone|phone]], passenger, or even nap, they might be unable to intervene properly when needed.<ref name="bbc.com"/>
