Just like TSLA is going to beat the big car companies at electric cars, so too will GOOG beat them at self-driving ones.
The electro-mechanical and mechanical aspect of a self-driving car is the easy part; it is the software that will be where the real innovation occurs, and Google has arguably more software expertise than any other organization on the planet, and much, much more than any car company.
That's hilarious because Tesla doesn't exist outside the US where as today electric cars can be purchased via GMs Volt program e.g GM Volt, Holden Volt, Opel Ampera. Likewise when BMW releases their electric car it will overnight be available in countless countries through their vast dealerships and partnerships.
You are being naive if you think that technology alone is all you need in business.
