That is literally defensive driving.

One of the really annoying things we inherited from reddit are the crowd of idiots who think the entire world can be summed up in a driver’s ed manual. Sometimes that manifests as “Driving 5 miles below the speed limit is the safest way to drive” and sometimes it manifests as… a jackass who is flooring it and swerving around traffic while flashing them with their signals because… they are maintaining the flow of traffic in the middle lane of a three lane highway?

The reality is that it doesn’t matter what the law is (unless a cop is visible). The other person getting a ticket is a weak consolation when your car is totaled and you are potentially crushed by all the god damned monster trucks on the road.

Defensive driving is about protecting yourself and, by association, the other drivers on the road. If the flow of traffic is that everyone is going 90 on a 60? You should at least be going 80 if you at all feel safe doing so because the alternative is increasingly aggressive drivers around you and an increasing likelihood of getting rear ended by someone who decides they want to pass on the right without looking ahead.

And same here. I’ve more or less learned to ignore turn signals when I am at an intersection. People aren’t turning right until they slow down and ACTUALLY start turning right. Doesn’t matter if their blinker is on because it might have been on for the past ten miles or they realize at the last second it is not the turn they want.

And that also applies to highway. I genuinely forget what the driver’s ed manual said, but let’s say that you are supposed to try to stay in the rightmost lane unless you are actively passing and the idea is that the left lane is for passing the people passing in the middle lane (that sounds wrong to me but, again, no idea). Fuck the law. Because people will randomly slow down 30 miles at a time when they start trying to read the signs to figure out what exit they are in. And “the rules of the road” are generally that the right lane is for getting on and off the highway, the middle lane is for traffic moving “at speed”, and the left lane is for passing… or driving 20 below the speed of the middle lane because you are the best driver ever but forgot what you were doing.

At the end of the day: it is about minimizing collisions (and, increasingly, lunatics with guns taking pot shots at you for existing). And a jackass who is swerving around and trying to shame people by flashing their blinkers is doing the opposite of that.
