Allstate Corp. said improved technology will eventually give the auto insurer a chance to boost revenue by selling customer driving data, much as Google Inc. profits by collecting information on those who use its search engine.“There are lots of people who are monetizing data today,” Allstate Chairman and Chief Executive Officer Tom Wilson said Thursday at a conference in New York held by Sanford C. Bernstein & Co. “You get on Google, and it seems like it’s free. It’s not free. You’re giving them information, they sell your information.”
