Yep, some incidents may be caused by human drivers being extra aggressive around the waymo. I work in this industry and this definitely happens. That said, weird / unexpected braking is a frequent problem for self driving cars too.
I was hit by this exact scam this weekend. Hilariously, they didn't even get the photo right, and sent me a picture of some neighborhood I had never seen.
This is all correct. Stats lie. Crime is an extremely localized issue, so it's easy for people to handwave away if they are in an area that doesn't experience it.
It is common for practitioners of Muai Thai and other kickboxing styles to harden their shins by whacking them with hard objects, or rolling something hard like a bottle across the bone. Sparring and hitting the heavy bag also harden your bones over time.
Kicks are normally blocked with the lower leg in Muai Thai. This often results in shin-on-shin contact which can be very painful for both fighters. So the point isn't so much to prevent full bone breaks (which are very rare) as to toughen the bone enough to handle this abuse... and make sure it hurts more for the other guy than it does for you.
Yeah, it would be a small advantage at best. Leg kicks very rarely break bones, usually they rely on causing pain and damage to tissue. And surgery will result in lost training time, plus the risk of something going wrong long term...
Some background here: in the autonomous vehicles world, it's common to split things up into 'perception' (detecting things around the car and creating a world model), 'planning' (deciding what to do), and 'controls' (giving gas, brake, steering etc so the car smoothly follows the plan). Saying telsa is using AI 'controls' here is probably a misnomer, Musk's statement indicates they are moving the entire planning stack to a NN.
'End to end' is also a bit misleading, as this usually indicates that perception and planning are fused into one network. They aren't doing this (which is probably a good idea), it's only 'end to end' from the planning and possibly controls side.
Well, this took place in canada. That said, amazon warehouse employees have no leverage and are easy to fire, which I suspect leads to a culture of 'follow the rules or else'.
