Wow RIP to the skater, it's crazy such a quick instant could end so tragically.
I skate in the street every day, keeping my head on a 360 swivel and I get out of the way if I see a risk. Just the other day I was skating down a hill and cut it onto the sidewalk then carved around a corner and almost pitched myself into a lane of traffic that would have had me right in line of a uhaul doing 30mph. Shit happens fast and all too often the cars aren't in the mindset that they are protected by 4000 lbs of metal around them and you have NOTHING.
