Shares of Uber and Lyft have come under pressure as Alphabet's Waymo expands autonomous vehicle testing to 10 new cities, including Las Vegas and San Diego.

Waymo, the self-driving division of Google parent Alphabet, announced Wednesday it plans to bring its autonomous taxis in San Diego this year.
