Warren Buffett's Geico now wants to track drivers, just like some of its biggest competitors do. Geico has launched a telematics offering, called DriveEasy, in certain states, Credit Suisse Group analyst Mike Zaremski said in a research note Tuesday. A phone app tracks driving habits and gives individuals a score and tips, according to Geico's website. While Geico has historically offered discounts to drivers for staying accident-free for five years, the app would be more interactive, using the phone to track trips. Rivals including Progressive Corp., which Buffett has called "well-run," and Allstate Corp. have long used programs to track drivers and encourage better behavior. — BLOOMBERG NEWS
