Brazil's President Dilma Rousseff capped off her U.S. tour on Wednesday with a visit to Silicon Valley, where she met with top technology executives and took a ride in Google Inc's self-driving car. Rousseff used her visit to strengthen ties with U.S. technology companies after visiting Washington, D.C. and New York City earlier in the week.
