Self-driving car company Cruise Automation is rushing to create a new autonomous vehicle with the help of one of the largest names in the automotive industry. Honda said it will invest $2.75 billion into Cruise's autonomous vehicle operations over the next 12 years, an infusion that arrives several months after the Japanese firm SoftBank announced a $2.25 billion investment in the company. Both investments bring the four-year-old company's valuation to a whopping $14.6 billion, General Motors said in a news release Wednesday. Cruise Automation -- which is already building a fleet of autonomous vehicles that could hit American streets as early as next year -- is a subsidiary of GM. The Detroit automaker's stock was up nearly 2 percent Wednesday.
