It has to be nation wide in at least 45 states, it also needs to be a comparable price to what Uber is now ( so like 30$ or less for a 10 mile trip)

1) When you scale from individual autonomous devices to vast networks of them you run into emergent phenomena that you simply could not predict ahead of time.

2) You have to spend enormous engineering effort protecting incumbents. E.g. there has been a ton of work on figuring out how to protect wireless microphones used by churches and stadiums. They are intermittent and have a "dumb receiver" (that never transmits), making them very difficult to handle using a "listen before talk" approach. And that's for fricking church PAs. Imagine the push-back when your technological edge case runs over a kid.

3) You can't deploy commercially until you change the regulatory regime. That can take years to decades if you're asking for seismic shifts in policy.

I would predict another 5-10 years before the technology works correctly at scale, rather than under controlled conditions. Then maybe another 5-10 years after that for limited regulatory approval, and maybe 10-25 years for widespread regulatory approval. I don't expect to be able to catch a self-driving cab in New York or Chicago before 2040.

[1] The end goal was technologies that could obsolete fixed spectrum allocation by letting networks of cognitive radios sort out for themselves what frequencies to use. There are various narrower applications, such as technologies that can take advantage of TV "whitespaces."

Not yet.

Based on what I know of Google's efforts, I think your three-year horizon for Tesla is, well, optimistic. As many miles as Google has logged, they're not testing at highway speeds yet -- I don't think their driverless prototypes (as opposed to the modified Lexus SUVs) are even capable of highway speeds. Also, AFAIK, they're only testing cars in Mountain View and Austin, which means there's a lot of weather conditions -- and to some degree terrain -- that they haven't had to accommodate. The most recently-given figures they've supplied that I can find is that they expect to be able to commercialize their technology between 2017 and 2020 -- and they've been working on this project since 2009. Tesla'a engineering is good, to be sure, but I would be really surprised if they beat Google to market in this area.

Now, once somebody really does start offering these for sale to the general public (or just to taxi/rideshare companies or etc.), the answer to your question shifts from "not yet" to "yep."
