Tesla is slow in reporting crashes and the feds have launched an investigation to find out why

Federal car safety regulators opened an investigation Thursday into why Tesla has repeatedly broken rules requiring it to tell them quickly about crashes involving its self-driving technology that may soon be deployed in millions of its cars on U.S. roads. The National Highway Traffic Safety Administration said “numerous” incidents involving Tesla's driver assistance and self-driving features were submitted far too late — several months after the crashes instead of within five days as required. The probe comes two months after the electric vehicle maker run by Elon Musk started a self-driving taxi service in Austin, Texas, with hopes offering it nationwide soon.
