text: A disruption within the human brain causes an individual to lose concentration or focus while driving. For example, driving a vehicle and talking to someone on the phone cannot be given the same amount of equal attention at the same time. For example, if the brain, of a driver, is focusing on a conversation on the phone, he or she may not notice the red light because he or she is looking at the phone versus straight ahead. It is virtually impossible for an individual mentally focus one hundred percent on more than one thing at a time. People cannot multitask where there is optimal focus and effectiveness. The brain handles tasks sequentially, switching from one task to another. Yet, the brain is incapable of juggling focus or attention simultaneously. .
