Ugh that's awful, asa.
A couple months ago I saw a kid on a motorcycle get hit by an SUV on W Kennedy. He flew off the bike, and went through a metal decorative fence after his helmeted head bounced off the pavement at least 4 times (saw the marks on the helmet).
He was under 21 so luckily had to follow the helmet law, and also had thick jeans and a long sleeved jacket on. He was conscious and just seemed to have a hip/leg injury. I had to stop because I thought he might be really bad off. I called his mom because he didn't want to worry her, but I got him to agree because you never know about head injuries, and she got to talk to him (through the helmet lol).
