Though I guess Google/Uber are probably getting significantly higher resolution data than Tesla/MobileEye/etc since you can't stream all sensor data back to HQ over LTE.
I think a lot of these articles are driven by the fact that Google has been working on this for so long and yet we have upstarts that are getting cars on the road in a fraction of the time.
It's very possible that Google overestimated the problems with Level 3 Autonomy and the public backlash associated with it and building L3 tech as an on-ramp towards L4 may turn out to be the correct path to market and funding further development effort.
