While some have projected how many traditional vehicles they can displace, I don't think anyone really knows how that'll play out. I doubt any of these companies will go making bets that obviously rival the scale of traditional vehicle sales/ownership at the time they're made, especially before they get a sense of how reliable AV transit affects the decisions individuals make about car ownership as they face major maintenance, repairs, and replacement.
I've read one projection that says each could replace 10 traditional vehicles. If that worked out, it seems like a bet on 10m vehicles, enough to replace all 100m sold worldwide, would be astonishingly bold. If you assumed an initial scope of the entire US, the equivalent bold bet would be 1.7m vehicles. If you reduced the scope to California, that bet would be about 200k vehicles. If we guess that the difference between "astonishingly bold" and "bold" is an order of magnitude, these would be reduced to 1m, 170k, and 20k...
Specifically, this section:
"According to the filing, Google and Motorola began discussions about Motorola's patent portfolio in early July, as well as the "intellectual property litigation and the potential impact of such litigation on the Android ecosystem".
Although the two companies discussed the possibility of an acquisition after the initial contact by Mr. Rubin, it was only after Motorola pushed back on the idea of patent sale that the acquisition talks picked up steam.
The turning point came during a meeting on July 6. At the meeting, Motorola CEO Sanjay Jha discussed the protection of the Android ecosystem with Google senior vice president Nikesh Arora, and during that talk Jha told Arora that "it could be problematic for Motorola Mobility to continue to exist as a stand-alone entity if it sold a large portion of its patent portfolio".
In connection with these discussions, the two companies signed a confidentiality and non-disclosure agreement that allowed Google to do due diligence on the company's patent portfolio."
