DETROIT (AP) — Computer chip maker Intel paid handsomely for a piece of the next big thing Monday as it offered more than $15 billion for Mobileye, an Israeli company at the forefront of autonomous vehicle technology.

The purchase, scheduled to close by year’s end, creates another major player in self-driving technology as traditional automakers and tech companies vie to put the cars into public use. Most companies have predicted autonomous vehicles will be carrying people in the next three-to-five years.

The big investment by Intel validates predictions that autonomous cars will someday come in large numbers, signifying a sea change in the way we all get around, said Timothy Carone, a Notre Dame University professor who has written about the future of automation. “Major players are finding ways finding ways to position themselves for a change as seminal as the personal computer revolution,” he said.

Self-driving cars are about to face their toughest test.

LOS ANGELES (AP) — Cars with no steering wheel, no pedals and nobody at all inside could be driving themselves on California roads by the end of the year, under proposed state rules that would give a powerful boost to the fast-developing technology.

For the past several years, tech companies and automakers have been testing self-driving car prototypes in neighborhoods and on freeways. But regulators insisted those vehicles have steering wheels, pedals and human backup drivers who could take over in an emergency.

On Friday, the state’s Department of Motor Vehicles proposed regulations that would open the way for truly driverless cars.
