Phil gave the full accident story on August 22, 2019 during playing Judgment.
He had just got on the highway and changed to the left lane while going "35 to 40mph", the speed limit was 55.
Phil also has never worn his glasses while driving and has always been legally required to wear them while driving.
Basically Phil cut someone off, was driving at or below the highway minimum speed in the passing lane, is blind as a fucking dingbat, freaked out and "swerved back and forth across both lanes 3 or 4 times."
Oh, and somehow none of this is his fault. Nothing he could do. "The guy must've been going 100mph!!!" The guy certainly couldn't have been driving 55mph when blind-ass granny Phil suddenly cut him off doing 35mph, nope the dude was totally going "100mph" according to Phil "World's Most Humble & Reliable Narrator" Butnell.
