That is exactly the same acquastion we as cyclists throw at car/van drivers. Get out of my way, I've paid my road tax etc etc. Replace ebike with souped up Corsa (or whatever the local boy racers are driving this week) and I doubt for one moment anyone would have any sympathy for the car driver.
It's not a 'get out of my way' scenario at all.
That would be an appropriate critique of the cyclist who recently tried to plough through a gaggle of pedestrians beeping his airhorn and got stung for £100k of costs when he hit one.
In this scenario she walked out alone against the lights briskly into the middle of a main road without looking.
Looking at the video, he had no real chance of avoiding her IMHO.
He might have had a better chance had he been going more slowly of course (or at least would have done less damage) but the traffic conditions were not generally shouting out 'danger pedestrians likely to stride out in front of you' from what I can see.
If you view him as a cyclist he is riding an illegal machine and going too fast.
Viewed as a human being he flees the scene and comes across as a scroat.
But viewed as someone on an electric moped the only question for me is his speed as compared to the rest of the traffic flow. We don't get to see enough of the CCTV to see what speed cars, vans and mopeds/motorbikes are doing down that stretch.
But all of them would be much more deadly.
Force=1/2 mass x velocity^2.
At 30kg and 30mph (13.4m/s) he's hitting her with a force of just under 2700N.
A mini at 20 mph would hit at 52000N.
And that is why death by bike is super rare compared to by car and makes national headlines when it does happen.
