Android O API 26. Newly added Location methods don't work as needed

I'm using Android O Developer preview 4 - API 26

Device - Google Pixel XL

And seems like the new features such as:

• hasSpeedAccuracy() always returns false
• getSpeedAccuracyMetersPerSecond() always returns 0.0
• getBearingAccuracyDegrees() always returns 0.0

for both fused and gps location providers. I've tried it while was moving in the car. So I have speed and bearingthemselves but don't their accuracy.

Am I missing something?

See docs here

Thanks!
