The top U.S. auto regulator has opened an investigation after a Tesla using an automated driving feature slammed into a Texas home at high speed and killed a 76-year-old woman standing inside.

The Tesla CEO is rolling out robotaxis using automated software in several U.S. cities this year. Tesla did not immediately reply to a request for comment.

Yet such an approach carries the risk of more violent swings in stock and bond prices, analysts say, and ultimately higher interest rates for consumers and businesses.
