Unusual motor vehicle suicides

Abstract:
A review was undertaken of cases in which motor vehicles were used to commit suicide. While the most common methods involved carbon monoxide toxicity or the sustaining of multiple injuries, three unusual cases were found involving: (i) hanging from a car seat belt, (ii) self immolation inside a car, and (iii) setting up a crash situation. The latter two cases were used as a backup to drug overdose. Problems that may occur in determining the manner of death are described.

Narcolepsy
Narcolepsy is a chronic sleep disorder characterized by pervasive, uncontrolled sleepiness and other sleep disturbances. One of its hallmark symptoms is an abrupt transition to REM sleep upon falling asleep, which causes symptoms typically associated with this phase to occur unexpectedly during wakefulness. These include the following symptoms, which typically last from a minute or two to half an hour.
Back EMF
Generators convert mechanical energy into electrical energy, whereas motors convert electrical energy into mechanical energy. A motor works by sending a current through a loop of wire located in a magnetic field. As a result, the magnetic field exerts a torque on the loop. This rotates a shaft, extracting mechanical work from the electrical current sent in initially. When the coil of a motor is turned, magnetic flux changes through the coil, and an emf (consistent with Faraday's law) is induced.
