Greg Migliore, Editor-in-Chief of Autoblog, discusses Aston Martin's latest announcement that all of its cars will be electric by 2019 and that it will go fully hybrid by 2025. We ask Migliore whether this announcement is a threat to Tesla, a leader in the EV industry. He notes that Tesla should feel threatened by all companies smart enough to make the move into electric, including Aston Martin, Honda, and Volkswagen.
