WASHINGTON, Nov 15 (Reuters) - Tesla Inc (TSLA.O) told U.S. auto safety regulators it has reports of two new crash fatalities in Model 3 cars tied to advanced driver assistance systems in the month ending October 15, data released Tuesday by the government shows.The National Highway Traffic Safety Administration (NHTSA) in June began releasing data provided by automakers on reports of crashes tied to driver assistance systems like Tesla's Autopilot.The agency has emphasized crashes are tracked by individual automakers in different ways and discouraged comparisons of performance among automakers partly due to lack of comprehensive metrics to track how widely each system is used or how crashes are reported.It has said Autopilot allows vehicles to brake and steer automatically within their lanes but does not make them capable of driving themselves.In June, NHTSA upgraded its defect investigation into 830,000 Tesla vehicles with Autopilot, a required step before it could seek a recall."
