Can you think of examples where a state has an interstate 3di, but the root 2di doesn't enter the state?
Examples:
I-535 crosses into Superior, Wisconsin, but I-35 never enters Wisconsin from Duluth, Minnesota.
I-287 enters New Jersey from I-87 in New York
I-275 enters Indiana near Cinncinati, but I-75 remains in Ohio
I-155 enters Tennessee from I-55 in Missouri
I-129 enters Nebraska from I-29 in Sioux City, Iowa
I-95 does enter the District of Columbia's airspace for less than a quarter of a mile, but for practical purposes you could probably list I-95 and DC (I-295 and I-395 are partially in DC and I-695 is entirely within the District). Or at least you could give it an honorable mention. I'd wager 99 percent of people who use I-95 over the Wilson Bridge have no idea they're passing through DC.
honorable mention: I-395 enters Massachusetts somewhat far away from I-95. the 95/395 connection is in Connecticut.

However, I-55 does enter Tennessee in the Memphis area. There could be a separate category for 3dis that enter a state independently of their parent 2di and never meet their parent 2di in said state. There are plenty of those examples as well such as I-395 in Massachusetts entering independently from I-95 and never meeting either I-95 or another I-x95 connected to I-95 within the state.
I-684 in CT is a 'independent' 3di, not meeting it's parent, as are I-276 and I-278 in NJ (though I-278 doesn't meet it's parent at all).
I-195 in MA doesn't meet I-95, but does meet I-495.

Another honorable mention - I-195 in Massachusetts, which leaves I-95 in Rhode Island and connects to I-495 in Wareham. Any other states where a 3di connects to a different 3di of the parent 2di, but does not then reconnect to the parent 2di?
How close would I-78 (and I-278/678) in NY be to qualifying? I.e., how long is it in New York?
Can't forget California, or is there an I-38 somewhere in the state?

not a multistate example, but I-175 and I-375 in Florida both spur off I-275.

Not a state, but the aforementioned I-695 in the District of Columbia connects to I-395 at one end and I-295 at the other. It doesn't connect to I-95 at all, although in fairness I should point out that once upon a time I-395 was I-95, so back then there was a connection.

In California: I-280, I-380, I-980, I-105.
If interstate designation matters, then you could argue I-210 would make the list, since it changes to CA-210, and connects to it's parent route under that designation.
Eastbound, NY's I-78 is 1.2 miles. Westbound, it's 0.8. None of this mileage is freeway, nor does it go anywhere near any I-X78.

Your name includes "english" but you can't correctly use apostrophes?

Also, I-795 in Maryland and I-990 and I-590 in New York.

I-275 & I-196 in Michigan

I-275 & I-196 in Michigan
I-196 connects to I-96 and I-275 connects to I-75 at the south end, so I don't know what you're smokin' ;)
My bad. Didn't read the whole post. I saw "doesn't reconnect to the parent 2di".

Which is a problem for I-196 why? (It's not even a problem for I-275, since both ends are at Interstates.)
Virginia doesn't have any...though it could one day get an "honorable mention". If US 29 near Danville ever gets upgraded to I-785, it'll fall into the category of entering the state independently and not connecting to I-85 within VA.
Back here in 2013...I-370 in Maryland also gets an "honorable mention" for connecting to a 3di (I-270) but not I-70.
Whenever PA gets that I-95/ I-276 interchange done in Bensalem, PA that will finally link the two I-95 segments together, I-295 will not be connected at all to its parent in New Jersey. Remember that I-295 is not interchanged with the NJ TPK Pennsylvania Extension and when the PA EXT becomes I-95, they will cross, but not interact with one another.

My question stands. Why would I-196 not returning to I-96 ever be an issue?

Who said it was? It was mentioned as fitting the (misunderstood) topic, not as being a problem or issue.
I believe your point is that any odd 3di should fit the topic (again, misunderstood as not connecting to the parent 2di), which is true, so there would be a lot of answers. Good thing we're not discussing that question!
I think the issue is that there is nothing at all significant about I-196 meeting its parent only once, so even misreading the topic shouldn't cause it to be notable (then again, we do have the "states with 3dus but not parent 2dus" topic).
