Self-driving cars: California is already prepping its roads
California’s state highway management system is now one of the first systems anywhere in the world to be actively changing its operations to better suit self-driving cars.

Caltrans Director Malcolm Dougherty, in an interview with KPCC Southern California Public Radio, explains: “The automated vehicles (AVs) can follow lane lines. They can’t follow the Botts’ Dots, so we’re actually changing our delineation standards to go away from the Botts’ Dots which we’ve been using for decades because AVs have a difficult time following those.”
“All of our lane lines are going to get thicker,” Dougherty continued “Today our lane lines are only four inches thick. Now every lane line we lie down going forward is going to be six inches thick. I’ve already started to see some of this transition.”
San Francisco Business Times provides more detail on the makeover to make California’s roads more friendly for self-driving cars: “Dougherty said that the lane modification will happen as roads and highways get new construction or standard re-striping done — and added that the agency aims to have the state’s highways and interstates modified within the next two to three years. California has around 50,000 miles of roadways”
