LAS VEGAS – As New York taxicab drivers continue to fight new requirements to install GPS, drivers in Las Vegas are embracing an older surveillance technology, according to Information-Week magazine. Nevada State Attorney General Brian Sandoval has issued an opinion stating that passengers cannot expect privacy when they are entering and exiting taxicabs, clearing the way for the Nevada Taxi-cab Authority to draft new regulations requiring cameras. The Authority, which regulates cab companies in Las Vegas and surrounding Clark County, is expected to work out glitches of an earlier proposal within the next several weeks. The Authority is likely to ban dissemination of the camera images except in law enforcement investigations. Most area cab drivers support the measure, and officials estimate that half of the 2,000 cabs on Clark County roads have already installed the equipment, according to InformationWeek magazine. Several companies have already installed the cameras. There were 19 armed robberies in cabs compared with 64 the previous year. Homicide dropped from one to none. Authorities captured at least two men after onboard cameras captured images of taxicab thefts in progress. About 400 cars are equipped with DriveCam Inc. systems, which record unsafe driving events so managers can counsel their drivers.
