I have driven and ridden through that intersection from all 4 directions. That particular region is relatively flat with good sight lines. 108th, which goes east-west is a semi-major road.
Not to seem morbid, but whenever anyone in our local club has an 'incident', we like to circle to discuss the details. Not out of curiosity, but in order to help prevent something in the future.
In this spirit: the bike appears to be a *very* large 70s or 80s vintage derailleur-based bike that was clearly T-boned from the right. I see downtube shifters and quill pedals. I don't see a rear brake, but that may have come off in the crash. Do I see a Cinelli stem? This may have been the riders prized classic & vintage steed...
