I live in Southern California, and there's much that I love about living here, but the one thing I don't love is the bad drivers. I've lived all over the country, and I really do think that SoCal drivers rank among the worst. I see the following driving etiquette violations on a daily basis:
1) Tailgating. Drivers here have it perfected to a fine science. Personally, I don't know how they do it -- I work hard to keep an exact, safe distance between myself and the car in front of me (a looong distance in front of me). People who ride up other car's butts (especially my own) scare the heck out of me.
2) Related to the above is tailgating at night, by SUVs. This really, really annoys the heck out of me. If you're an SUV, please don't ride my butt at night, and flood the interior of my car with your headlights. It's blinding!!! I confess to slowing down, just to annoy them so they'll go around me.
3) Lack of turn signal usage. 'Nuff said. Nobody uses them out here. Well, except for me.
4) People who drive on the shoulder in traffic jams. This makes me so angry. What makes you so special that you get to a) break the law, and b) pass the rest of us law-abiding citizens by driving on the shoulder? This happens in every traffic jam on the freeway, all those self-entitled jerks, zipping along on the shoulder...
Anyone got any others that drive you insane?
Well, I'm in SoCal... grew up in LA, learned how to drive in LA, so I can handle being around the craziest drivers on the planet. My greatest flaw is that my road rage emerges from time to time and it's not pretty. I'm a reformed tailgater, so I can't complain too much about it. I actually leave plenty of braking room in front of me nowadays, but other drivers usually take it as an invitation for them to change lanes.
You're not the only one who uses turn signals. I do, too.

But...
cocacola35 captured it perfectly. Everyone in my So Cal area (I'm not in LA anymore) decides that a turn signal is a signal to speed up. That's already annoying, but drivers around here
really, really, really love to speed up, then PACE you by staying right around your trunk and backdoors. So... I put on my signal as a courtesy and drivers not only speed up, but they actually IMPEDE my efforts to change lanes.
I hate the xenon lights that a lot of SUVs and luxury sedans use nowadays. If they hit my mirrors and reflect into my eyes, it turns into an instant migraine. I don't know why, but those specific lights always give me splitting headaches.
Entitlement is my general gripe about drivers in this area. I was driving along the fast lane and a driver in the next lane ended up behind a big truck (why he didn't change lanes before he had to slow down, I don't know), effectively slowing him down about 30 mph slower than me. He was trying to change lanes, but I was already too close and my only recourse would have been to slam on my brakes. He tried to cut me off, but even he could see that it would have ended very badly. Since there was no one behind me, he could have just waited for me to pass by. Apparently, that wasn't what he believed, because he changes lanes after I passed and promptly flashes his high beams.
On the entitlement note, a lot of people here honk when you're stopped at a Yield sign... with oncoming traffic. I have literally turned around in my seat and gestured at the people behind me. It's not polite, but they're basically demanding that I drive into oncoming traffic so they can arrive at their destination faster. If you're going to ask me to cause a traffic accident, then I'm going to have an unkind reply.
As for shoulder driving... some of the shoulders here are reserved for transit buses during rush hour. BF tells me that, because the buses are using the shoulders clearly marked "Transit Buses Only", some cars feel they can do the same. What's going to happen is that a car is going to use the shoulder, stop when they want to wedge back into traffic, and a huge bus is going to come rolling up behind them. Buses don't have the shortest stopping distance and in a game of chicken between a bus and a car, I don't think many cars will win.
4) People who drive on the shoulder in traffic jams. This makes me so angry. What makes you so special that you get to a) break the law, and b) pass the rest of us law-abiding citizens by driving on the shoulder? This happens in every traffic jam on the freeway, all those self-entitled jerks, zipping along on the shoulder...
I also get angry at the morons that let these jerks cut back into traffic at the front of the line! That only encourages these self-entitled jerks to do this in the first place.
-People that see your turn signal and then speed up on purpose so you can't go into their lane. What is this pre-school?? Did I somehow sign up for some drag race with you by putting my signal on? Grow the #$%* up and just let me over!!!
-People that crawl in the fast lanes. This can cause accidents and road rage- why oh why can't these people move over into the lanes that are meant for slow moving motorists?? Apparently some of them must have slow minds as well.....
-For pete's sake, turn off your high beams if you are driving on a main street! I don't like being blinded because it may be hazardous to me and you.
People the crawl in the fast lanes absolutely infuriate me. Sure, call me a typical SoCal driver that demands that people drive faster. But... no one should ever slow down and block the flow of traffic. I was driving to work one morning and a man in a Jeep decides to cut me off and slow to 55 mph. Traffic around him was going at least 70, not to mention the actual speed limit is 65 (this
is Southern CA, y'all). We were in the second-fastest lane and there was no reason for him to slow down. Nothing in front of him and he had a fairly new Jeep, so it wasn't car trouble. I ended up passing him and when I did, I noticed that he had a very determined look on his face.
This is a guess, but based on the look on his face and the fact that he held that speed while other cars backed up behind him (I saw him become smaller and smaller in my rearview, with cars darting out behind him), I think he was determined to hold that speed. I honestly believe that he was trying to take a stance... like he was trying to let us all know that he will drive exactly as fast as he wants to, where he wants to. He didn't look scared or uncomfortable... just very, very determined.
Of course, I wonder if that will change when someone, frantically trying to get around him, slams into a car in the next lane.
On concert traffic: BF dragged me out of a Sarah McLachlan concert early (this was when
Afterglow came out and I hadn't seen her perform in 7 years) to avoid traffic. He also did this when REM performed at a local music festival and I was waiting for "It's the End of the World". He drags me and our friend out... the next day our friend emails us a headline: "REM performs with surprise guest Eddie Vedder". Guess what song they performed? He's absolutely zealous about avoiding post-concert/game traffic and we're all going to smack him at some point.
Behindbj, I actually teared up when I read your post. How tragic.
Sorry for the long post, folks!
