I have a lot of experience with highway driving that most of my friends don't have. Rules (from the USA) like only drive in the left lane when you are passing - ie. slow traffic keep right and never merge into another driver's blind spot are intuitive to me at this point. They make sense and make driving less stressful for all drivers around.
However, several of my friends, while conscious of the rules (guidelines?, laws?), are often forgetful or inconsiderate of other drivers. There have been many instances where I have felt uncomfortable as a passenger with my friends' habits of, for example, tailgating too close to the bumper of the car in front of them or not using their blinker to switch lanes. Time and time again, my friends' recklessness in these situations leads to "road rage" in other drivers who then become so offended that they MUST be reckless and angry back at my friend. It's an endless loop of rage and stress that is completely unnecessary.
I know being a backseat driver in itself is a curse of impatience, but if I feel like I'm in danger whenever I drive with my friends, I think it makes sense for me to speak up. The only problem is I am not very good at confronting these bad driving habits and need help.
There have been times that I have tried to be upfront and straightforward with my friends, saying things like "Bro, you should really move back to the other lane- there are three cars behind you that want to go 10mph faster" or "You should use your blinker, dude. That car in your blind spot may have been trying to merge too." But this typically just leads to them getting angry at me, their trusty passenger whose supposed to be on their side... I have also tried slipping passive advice like "Man, lately I've been feeling great and patient on the road because I've been giving everyone a TON of space" but they just smile and say "nice".
I'm open to all suggestions on how to become a better backseat driver. I'd mostly like to get different approaches on how I can confront their driving habits, but I could also use advice on how to improve my patience as a passenger. Thanks!
