While some proposed accident detection systems utilize the existing cellular network, they have traditionally focused solely on voice capabilities and have not gained wide adoption. Smartphones allow use of the existing voice and data infrastructure, without the need for additional in-vehicle hardware. Due to customers and manufacturers not having to purchase new hardware, it is possible that the adoption rate of a smartphone- based accident detection systems would be higher than non-smartphone alternatives.
