Condolences to the family and Rest In Peace.

Can you talk about the bike? I’ve never seen anything like that

Wow, that is so sad, and also very scary (as all of these are). May he rest in peace.

Not saying this is what happened here, but the level of inattentiveness, among drivers, is sickening. There's a busy road near me, that has a nice wide shoulder. During some of my runs, I have to run about a mile on this shoulder before veering off to my less busy route. I run against the traffic and watch the cars coming at me. Even though it is "rush hour" traffic time, it amazes me the number of people looking down at their phones while driving Either the head is down, or the driver is holding the phone up at the steering wheel, texting while attempting to drive. And its not just a few drivers. Its a large majority of the ones passing me as I run toward them on the wide shoulder. I'm truly surprised more pedestrians have not been hurt by inattentive drivers.

Custom built on account of the fact that he only had partial functionality on one half of his body. I believe the main triangle was from a Felt AR. Edit to add: actually it was more of a "conversion" than a custom frame. Basically a custom rear axle and triangle that braced to the seat tube.

The traffic by me has gotten so bad that it's basically bumper to bumper from 4:00pm to 6:00pm. It's a slow 5mph crawl. I'll often ride my mountain bike on the sidewalk (which nobody uses) up to the grocery store or gym (~2 miles away). I get quite an opportunity to look at drivers as I'm riding against traffic and I can confirm that ~1/3-1/2 drivers are looking at their phone.
