It expands at light speed. That’s fast enough that no computational processing can possibly occur before we’re dead. Sure there’s branches where it maims us and then stops, but these are incredibly subdominant compared to branches where the tunneling doesn’t happen.
Yes, you can make suicide machines very reliable and fast. I claim that whether your proposed suicide machine actually is reliable does in factmatter for determining whether you are likely to find yourself maimed. Making suicide machines that are synchronised earth-wide seems very difficult with current technology.
I could be wrong, but from what I’ve read the domain wall should have mass, so it must travel below light speed. However, the energy difference between the two vacuums would put a large force on the wall, rapidly accelerating it to very close to light speed. Collisions with stars and gravitational effects might cause further weirdness, but ignoring that, I think after a while we basically expect constant acceleration, meaning that light cones starting inside the bubble that are at least a certain distance from the wall would never catch up with the wall. So yeah, definitely above 0.95c.

No, vacuum decay generally expands at sub-light speed.
How sub-light? I was mostly just guessing here, but if it’s below like 0.95c I’d be surprised.

I’d also be surprised.
