A General Motors Co. executive credited Silicon Valley companies, including Alphabet Inc.’s Google car division and Tesla Motors Inc., for accelerating the development of autonomous vehicle technology and shortening the timetable for when safer self-driving cars hit the road.
 
 Richard Holman, a 30-year automotive veteran running GM’s foresight and trends unit, said Tuesday that three years ago most industry participants would have estimated 2035 as a reasonable timetable for self-driving cars. Speaking to a conference in suburban Detroit, Mr. Holman said now most people see that technology being deployed by 2020, if not sooner.
 
 Mr. Holman noted companies like GM and its rivals have been working on autonomous vehicles for several years, and said tech giant Google and electric-car maker Tesla deserve get credited for moving the industry along.
