>literally says "slow down"
You weren't paying attention.
>It does say to help him get in if it’s tight,
It says multiple times you have to monitor the situation even if it's you who's being overtaken. Including through the mirrors. That's the idea some of the people here can't grasp. "It's all drunk driver's fault, you can't do anything, so why bother?" Yes it's his fault, no you can at least try to do something.
>the truck is a lot closer to the car than you think
And probably uncomfortably close (as in "hit the brakes" or at least "move right" uncomfortably).
