In Puget Sound, Washington, a survey of drivers equipped with in-vehicle emergency communications found that 95 percent of respondents felt "more secure" with Mayday voice communications, and 70 percent felt "more secure" with data communications.

The Puget Sound Help Me (PuSHMe) Mayday System allowed a driver to immediately send to a response center a notification and location of incidents along with the need for any assistance. Of those drivers equipped with voice communications, 95 percent felt more secure while 70 percent of those with only data communications said that they were more secure with the system installed.
