He'd drunk 750ml of cognac. Cedars noted he was under influence and smelled of marijuana. I think he'd stopped at a weed shop at 11AM or so on day of accident.

He was going downhill on a sidewalk covered by trash. It's actually not totally clear the sidewalk issue was cause of accident. He hit a tree parallel to the uplift, the city wonders how that was possible, if he hit the uplift and pitched forward it would be weird to hit a tree parallel to the uplift. There were other issues on the hill (trash etc).

There had been no service records to fix sidewalk in 10 year search by city.

Smoking weed impairs you. He smelled of weed and stopped at a cannabis store. Even ignoring all this, he accelerated down this hill, never applied the brakes. I'm just pointing out some other factors that may have caused his accident other than the city being idiots.
