That's a terrible analogy. Firstly, that analogy is ridiculous: Alice doesn't necessarily see that Bob is on his cell phone, she's concentrating on the road and cars around her - not looking intently into the car next to her! In fact, being in a blind spot means that it's literally impossible for Alice to see that Bob is on his phone. So the answer is no, she doesn't bear any responsibility at all.
Secondly, you should be able to congratulate your daughter on Twitter regardless of your status as a public person.
I can't be held responsible for your actions. Making an innocent tweet about your daughter is not something you should have to be worried about. That's chilling freedom of expression! So you can't be a proud dad because some arsehole might threaten to rape your daughter? Give me a break.
Now I'm really confused. You're saying that if Alice is in Bob's blind spot, it is impossible for Alice to see Bob on his phone? Are we talking about the same blind spot?
I probably overstate that point, but it is less likely you can see they are on the phone. My point still stands - it's not the responsibility of the driver to peer into the car next to them to see their behaviour. In fact, that's downright dangerous.
I completely disagree, it's downright dangerous to not evaluate the behavior of other drivers around you. If I see someone aggressively changing lanes or tailgating, talking on their cell phone, or doing anything that looks risky to me, I mentally note it and keep as far away from them as possible. I'm frankly amazed anyone wouldn't do the same.
I agree that Alice in my example doesn't have any legal fault for the accident. Maybe this is a cultural difference, but as I see it she does share some responsibility for being in the accident if she didn't make a best-effort attempt using known-good practices to avoid it. All drivers share that responsibility.
I'm assuming you see it happening as you drive past. But do you look into each car intently to see what the driver is doing? I see drivers on phones, but I'm sure I don't see all of them. I'm normally aching the traffic and the way they are braking/swerving to determine if the driver is someone to keep clear of.
There is no cultural difference on this one that I'm aware of. In Australia you must be aware of what is going on around you on the road. But you asked about victim blaming - I think someone above expressed it better than me, and you thanked them for their post. That's the one I'm going with :-)
