For all those worried about watching, IMO, it is not all that graphic, and it is quite small and somewhat blurry. I mean, it is a through the windshield shot of a car hitting a running pedestrian and they bounce pretty hard, but there is no blood, dismemberment, or anything. And the person moves afterwards, so not clearly dead on the scene. A lot of us see A LOT worse in purportedly family entertainment. Just MO.
When my wife gets home, I’ll ask her for her opinion. She arbitrates A LOT of lawsuits involving traffic accidents. But I’m pretty sure she would agree with my assessment below (tho she could put it in clearer legalese.)
Are we discussing criminal or civil liability? In my state (IL) I’d imagine the driver would both get a ticket AND be liable for damages. A green light does not give a driver freedom to just blast through an interesction. In IL, I’m pretty sure (if folk insist, I may look it up) that the law states that you must ascertain whether an intersection is clear before proceeding. (Not sure whether the crosswalk/signal in the vid was an intersection or just a ped crosswalk.).
Heck, there is a weird wrinkle in that the ped was in a marked crosswalk BUT ALSO crossing against a signal. So maybe both the ped AND the driver would get tickets.
Another element is who struck whom, and who had the last chance to avoid the accident? The answer to both is IMO indisputably the car. Also, it appears to have been raining, which would further suggest the driver ought to have been driving more slowly.
This goes to something I’ve long thought, but few people have agreed with me. Being a good driver and avoiding accidents TO SOME DEGREE depends on good luck. I bet nearly every one of us has done something like the driver in the vid at least once. If the driver had been a second earlier or later, nothing woulda happened. Every driver is momentarily distracted at times. Most of the time we are fortunate that AT THAT INSTANT someone doesn’t dart into the street, the driver in front doesn’t slam on their brakes, etc… But I digress…
Of course, the pedestrian in the vid was a fucking idiot - running across the street, against the signal, with ZERO view of whether traffic was coming. I have ZERO sympathy for them, but I still think their negligence is outweighed by the driver’s. And we haven’t even discussed distinguishing contributory vs comparative negligence… 
As a bike rider, this sorta thing happens ALL THE TIME. Our local bike paths cross some 4-lane streets. All have marked crosswalks, and some have buttons to signal flashing lights. But even if the folk in the lane closest to you stop and wait, you have to wait to see if the fok in the second lane will do so as well. A large percentage of the time they appear to continue without slowing, apparently oblivious to the clearly visible bikers waiting at the side of the road, and unconcerned with whatever reason the other drivers might be stopping. Heck, often driver in lane 1 stops and waves you across, and the driver BEHIND that car whips out into the second lane and speeds past the stopped car. People are fucking idiots. No one is looking out for you as well as yourself.
Similar concerns are one reason I generally disfavor cars thinking they are being kind or generous or courteous and stopping and waving bikes through, when the car has the right of way. This driver might think they are being courteous. But the other drivers have no idea why the first driver isn’t just following the rules of the road and allowing the bike to wait until their turn.
Bottomline, either criminal or civil liability involve resolving various questions of fact to be resolved by a judge/jury. There is no simple unambiguous answer.
