Rule changes announced by the Trump administration this week could allow automakers to report fewer crashes involving self-driving cars, with Tesla potentially emerging as the main beneficiary.

The Trump administration will allow self-driving cars an exemption from some safety rules for testing amid a push to compete with China, Transportation Secretary Sean Duffy said Thursday.

The Trump administration announcement that it aims to speed deployment of self-driving vehicles by exempting some from certain safety requirements and easing rules requiring reporting of safety incidents sent Tesla shares up nearly 10% on Friday.
