Google is not a car company. I don't see how that would be good for either of them. A joint venture seems more likely. Money is only part of the equitation and Elon Musk actually want's to change the status quo so we don't suffocate with CO2. Assimilation politics would not further that goal.
A collaboration would be very beneficial for both parties though. Tesla and Google could focus on what they can do best and bring out a product in a joint venture that unifies they're strength sharing the profit.
They are a technology company. I think Google should keep Tesla separate, and with very subtle non-intrusive brand insertion - e.g. "Just a company Google owns" They would collaborate too. Everything you say is true, and no reason that should stop Google from buying them. Especially since Google's getting into self-driving car and Google Glass-technology, etc..
They are developing the technology to make car self-driving. They are not developing the cars. They use Toyota Prius and I think some Lexus model too. I could see them partnering with Tesla to make it the first company to use the technology though.
Google's not a phone company either, but they sell phones. Why would you not expect them to sell cars when they're obviously dumping so much money into auto technology?
Because that auto technology is not meant for users. It's meant for them to get a more accurate and up-to-date street view for Maps. Android is an extremely user-facing technology, and furthers their efforts to control as much of the mobile ecosystem as possible.
Buying Motorola to support their growth in mobile makes sense. Buying a car company to support a side project doesn't make any sense.
A collaboration would be very beneficial for both parties though. Tesla and Google could focus on what they can do best and bring out a product in a joint venture that unifies they're strength sharing the profit.
But maybe I'm naive?
