The Tesla Motors Inc (TSLA)-Google Inc (GOOG) Link

Google, on the other hand, is up nearly 25% year-to-date, and its Glass project can make a meaningful impact on its bottom line, and subsequently, its share price. BI Intelligence forecasts “Google Glass will go mainstream within a few years, as the price drops and the design begins to resemble normal eyewear,” estimating $15-20 billion in cumulative sales by 2019. Google made just over $50 billion in revenue last year alone.

Final thoughts

Of course, Sahas Katta’s start-up Pepperdeck isn’t an option for investors just yet, but another way to get exposure to the budding smart car industry is, surprisingly, with Apple Inc. (NASDAQ:AAPL). Apple’s iOS7 is set to provide much-anticipated integration with 14 partnership automakers, including Chevy, Ferrari, Acura, Honda, Hyundai, Infiniti, Kia, Jaguar, Mercedes-Benz, Nissan, Volvo and BMW.

This technology, which is touted as being truly “eyes free,” won’t have the impact on Apple’s bottom line that Glass will on Google’s, but it’s an interesting growth driver worth considering moving forward. Trading at less than 10 times forward earnings and a PEG below 0.5, a strengthened “eyes free” presence could boost Apple Inc. (NASDAQ:AAPL)’s 39.2% market share in the smartphone platform space—via comScore—closer to Google’s, which rests above 52%.

Either way, we’ll be watching closely, keeping Tesla in our sights as well. See 6 Tesla images that will give you the real story here.
