Totally agree on the DEFENSIVE driving, regardless. Moving along.....you could not have been in a worse place in this country, IMHO, than I-55 and I-40. We moved to Memphis in '89 and it was all under construction. 25 years later it's still torn up with no completion in sight. Would rather drive in Chi! And, so much for "gentile southerners"....Memphis has some of the worst drivers I've ever seen. They're rude, discourteous, are under the opinion that faster is better and will cut you off in a heartbeat. If there is any possible way to get from Point A to Point B without going through Memphis, we do it. For future info, if you can work it, get off I-55 at I-155 toward Dyersburg - this is north of the interchange from H***. South on Hwy 412 and either end up in Jackson or cut through on some county roads. Yes, it's out of the way, but lots easier on the nerves....and the vehicles.
In '89 Memphis was a different place....very, very glad to have moved east on I-40. Sorry for the jangled nerves, but you escaped unscathed. Hope not to have offended any Memphians, but you know I'm right.
**OP, just noticed you're from LR, sorry but you're out of luck avoiding that interchange unless you go zig zag to Helena, AR and across that bridge. The bad news is that there is/was construction just south of Memphis on I-55, so you have another opportunity to get slammed.
