Not on the highway. Which is why stopping a vehicle on it, driving a scooter/buggy/bicycle on it, or crossing it on foot is illegal. Because if you do these things, you are likely to be hit--it is engineered in.
But to repeat, to be convicted it only had to be true that her car being there contributed to the death. Which is rather hard to argue against? You can argue perhaps that the law is unfair, but the jury seems to applied it correctly.
The next question is whether turning down a plea with a short custodial sentence and rolling the dice will pay off for her.
I'm torn on contributing. I see the point, but I also think you're meant to leave room and be aware and prepared to stop, because there may be an emergency or god knows what. He was exceeding the speed limit by a good bit and I'd argue wasn't aware - cars were able to avoid her, he was on a bike, which seems logically should have been better able to, not worse, as it's more maneuverable.
As to the stopping, I agree it wasn't the best choice, but she saw an emergency: ducks in danger. I get the prosecutor doesn't think that matters, but to her, it clearly did. Had she pulled over on the opposite shoulder and tried to dart across and back herself, with ducks, it may have been more disruptive, or she might have thought it'd have driven them into traffic, I dunno.
I know someone was once driving on a major highway in the U.S., at night, and saw a weird glint, so slowed down. It was lucky he did, as the glint was a car parked sideways across two lanes of the highway ahead of him - some moron had realized he was going north when he wanted to go south and thought he could make a U-turn, so tried it, then realized there was a concrete divider, so stopped. Headlights were aiming into the median and dulled by the grass along it. That, I'd say contributed, had there been an accident, because wtf.
This, in daylight, parked (yes, you're not meant to park there, but it can happen for universally-reasonable reasons), door open (I agree she should have had blinkers on, obvs.), I dunno, I'm conflicted.
