Hmmm. Lots of misinformation here with sprinkles of unrealistic expectations AND realities at the moment.
Let's define a few things:
Pulled from the internet
"
Level 0: This one is pretty basic. The driver (human) controls it all: steering, brakes, throttle, power. It's what you've been doing all along.
Level 1: This semi-autonomous level means that most functions are still controlled by a driver, but some (like braking) can be done automatically by the car.
Level 2: In level 2, at least 2 functions are automated, like cruise control and lane-centering. It means that the "driver is disengaged from physically operating the vehicle by having his or her hands off the steering wheel AND foot off pedal at the same time." The driver must be still always be ready to take control of the vehicle, however. So, level 2 means two functions automated. Easy to remember, right?
Level 3: Drivers are still necessary in level 3 cars, but are able to completely shift "safety-critical functions" to the vehicle, under certain traffic or environmental conditions. It means that the driver is still present, but is not required to monitor the situation in the same way it does for previous levels. Jim McBride, autonomous vehicles expert at Ford, said, "the biggest demarcation is between Levels 3 and 4." He's focused on getting Ford straight to Level 4, since Level 3, which involves transferring control from car to human, can often pose difficulties. "We're not going to ask the driver to instantaneously intervene—that's not a fair proposition."
Level 4: This is what is meant by "fully autonomous." According to the DOT, level 4 vehicles are "designed to perform all safety-critical driving functions and monitor roadway conditions for an entire trip." It's what Tesla says will be
available by 2018.
*Level 5: It should be noted that some organizations, like the Society of Automotive Engineers (SAE), have their own
charts that refer to "Level 5" vehicles. This refers to a fully-autonomous vehicle that does not have any option for human driving—no steering wheel or controls.

So we are at Level 2 legally ATM. Level 3 will be the next case where you must be in the front seat, but you can nod off or play on your phone legally. If there is a situation the car can't deal with it will give you ample time to take control otherwise it will likely safely pull over and wait for input. To get to level 3 and 4 will require approval and to get approval is just a data game and we KNOW Tesla is ahead with that. Let's not mistake ALL players in the game have full level 4 even level 5 prototype cars out there. Google, Apple, Universities, Mitsubishi, BMW, and yes, Tesla does too. I gather from Elon's "blowing people's minds" comments that he's ridden in one. As someone mentioned though, some prototype is not suitable for the masses. It must be proven and then approved by the DOT. So far everything I've said is accurate, what comes next is speculation. Getting the right hardware (integrated beautifully) and redundant control systems, I think Tesla is ahead of the game by a year or so. Software is up in the air - So many management and talent personnel being traded right now between companies, it's crazy haha. Again, data should win the game here and we know Tesla is winning at this. It'll also be the first to mass market the AP 2.0 hardware and if the speculation that AP 1.0 data is no good, they will still be the leaders as there are no other mass market cars delivering this.
