If this would also mean I can drive at the max allowed speed and can't get fines I would actually like this. I don't really feel the need for speed anyway, the maximum allowed speed usually is fine for me. But some countries like France switch a lot between 130 and 110, so most of my speeding tickets are because I didn't see the 110 sign immediately and there is a speed camera.
If this solution let's you go a max speed with zero tickets I would use it.
Let say the ticket is 100 dollars thats like a millisecond of profit for Google. So what's the point, threaten them with revoking the robot taxi license.
