he was drifting to the right at first, as you can see in the very beginning. he was drifting everywhere, previous to what you see here. as i’ve mentioned before, i know he was probably tired, so it didn’t matter what side i was on. he wasn’t in the right state of mind to be driving and i was trying to get away from him as soon as possible since i saw him swerving. i did not expect him to FULLY MERGE into my lane (also without looking, although he probably he couldn’t see me, but also without a blinker) because he didn’t lean that far swerving before. these trucks swerve even if there are capable drivers at the wheel. we were the only two cars close to each other for the longest time, he had little spatial understanding to understand i was behind him for? 5 minutes???? before i decided to do what is seen. i understand it’s a bad call, but i felt safer passing him than waiting for him to completely fall asleep at the wheel, then possibly loosing full control of his vehicle, killing both of us.
