I've been there once, and I didn't die.Do you live in Sweden?
Why do you ask?

Well, OK, a=0.7 and m=80 (or so) and you've practically provided your own answer. But I don't know what you want to do with it.The point, I thought, is about the force required to stop and that is directly linked to mass with F=ma. You have calculated the acceleration, but to get the force (ie how hard to brake), you'll need the mass too.
If anyone's interested, there's a rather good explanation of the current case law here.
Not Sweden, but just over the other side of the Gulf of Finland in Helsinki they are very disciplined about use of crossings. Unlike here where we stroll nonchalantly out on a red signal if we think that the likelihood of instant death has fallen to a merely moderate level.Do you live in Sweden?
I think you say "Beam me down Scotty" and it goes from there.I take you know the exact circumstances then.![]()
When someone is standing at a crossing and wanting to cross, their behaviour is highly predictable. They are extremely likely to cross the road at some point.

I remember waiting at a pedestrian crossing in Helsinki for ages. There is no traffic in sight. Red man. Wait. Wait. Still red. Still no traffic. Still red. Wait ... Eventually my nerve snapped and I felt I just had to cross, so I strolled out into the road. Immediately a tram appeared, as if from nowhere, bearing down on me, and I had to sprint out of the way - feeling the Hard Stares of the waiting Finns on me as I did so.
Another thing I found was that the Finnish cyclists don't tolerate peds, even lost English ones, wandering aimlessly around on the cycle paths in Helsinki.
We have crossings in Crewe that simply don't change, even if you continually press the button in a frustrated sort of a way.Same in Hong Kong. They seem to have out-Britished the British. I'm somewhat embarrassed to sneak across on a red there, under the watchful gaze of the locals from their moral high ground
Define "without warning"....but if they go from walking down the street to walking across the road without warning then they should consider themselves lucky it was a bike and not a lorry + national selection in action.

Fits the example I gave. The warnings were mostly in the way they were messing about on the pavement.It's as I said, walking out without stopping and looking.
