True...if you give yourself ample space between you and the car in front of you you're fine. The problem is someone will change lanes in to that spot causing you to drop back further, which may wind up repeating the situation until you are 5-6 cars back from where you were lol...OR, the person behind you will not give ample room because they don't want people cutting in, want you to go faster even though you have 20 cars in front of you, or they're just stupid (hard to differentiate what their motive is). Buy some tires with good grip and you'll be ok, not necessarily rain-specialized tires but some good performance tires.
md...if you got the sense that Lafayette traffic can become congested you are right, and congested is an understatement depending on the road, conditions, and if any accidents are involved. The BIG problem with Lafayette's road system is that if an accident occurs there are normally no detours for traffic to take without going a good distance out of your way. When this happens it can be frustrating.
I too have driven in at least 22 states (been in 26 of them plus a few provinces in Canada) and LA's are the worst...I haven't driven on the east coast or in California though. I barely caught the NE corner of NM coming up here, maybe I'll make a trip to Santa Fe when I get back on my feet and compare the drivers there to Lafayette

I believe the big problem with Lafayette's drivers is that the congestion causes them to do things they wouldn't normally do if traffic actually flowed. A city that size should NOT have the congestion that it does. Heck, the traffic here flows better at rush hour than it does down there lol.
Also, I don't have much experience with this in other states save for Colorado (been too long since I've driven in Alaska so I'll leave it out)...but when there is road construction and the signs are posted a half mile in advance (or more) that one of the lanes is closed people will stay in the lane to be closed until the last second and try to cut in to the other lane at the last second. The people at the front in the open lane will sit there and let all these people in while the others behind them who followed directions are forced to wait...and wait...and wait. There are a few choices here...be one of the jerks who cuts in at the front or be one of the nice people who doesn't allow them in when you get to the front

They may try to muscle their way in but I've never found any who wanted to risk actually hitting my car...even with larger truck or SUV but boy they sure get mad

Now when I moved here I was utterly amazed that people did the exact opposite and moved over long before the lane ended
Btw, might want to make a map of where the red light cameras are and be aware that they have speed vans like AZ does (and probably NM). I know they are putting up a few more along Ambassador Caffery. People like to run red lights in Lafayette but the time between that light turning red and the other light turning green is usually very very short...plenty of accidents caused by this. I am impressed with the traffic lights here...the yellows are decently long in most places I have been allowing ample time to stop (people still run reds but not as much as I am used to seeing...i.e., 2-3 cars after the light is red) and there is about a two second delay from the next light turning green so even if someone does run a red light nobody else should be in the intersection. Oh, the pedestrian cross-walk timers make a handy tool to gauge how long before the light turns yellow if you have good enough vision to make out the numbers. Seattle had these too and I thought it was awesome even if it wasn't the intended use lol.
Humidity...it was interesting to me at first as well coming from an arid part of Alaska but the novelty quickly wore off lol. The heat never really bothered me (I am fair skinned due to my northern European heritage so I do burn easy though) it was just the incessant humidity that is inescapable outdoors. Don't get me wrong, I didn't hide in my home all the time...I spent plenty of time outdoors but even in the shade there wasn't much relief lol.
You really don't have to worry about the cops pulling you over to give you a ticket, that's basically been relegated to the Red Flex cameras and vans. I've seen more people pulled over here since I moved at the beginning of March than in my eleven years down there TOTAL (maybe a [b]slight[b] exaggeration, but not much). Most of those that were pulled over were in the smaller outlying towns or on the interstates. Watch the cops along I-10 from the TX/LA border east...they're not so "bad" on I-49 between Lafayette and Opelousas but north of that you need to be a bit more careful.
If you do move to Lafayette I hope you enjoy it...aside from the traffic problems it's a pretty nice town. Almost always some festival of sorts going on either in town or within a 30 minute drive and excellent food. People are pretty friendly too...not the friendliest I've ever encountered in my travels but for a city that size they're pretty nice
