Now I intend to take two weekday trips to New York. I go to Delta, and they say "Don't use this fare for weekday itineraries - you must stay in your destination city Saturday night." I say "No problem, two weekend trips." You somehow think that's different.
It is different.
When you buy the two separate airline tickets you are complying with the terms of each individual ticket in all cases when you fly the flights that are ticketed. Airlines have no monitoring or enforcement ability or authority over what you do with your Saturday night or between those flights. Whether you go out to dinner, sleep on a sidewalk, skip brushing your teeth, go to the dentist's office, or catch another flight to anywhere yo want at any time is not material to the contract of carriage.
Using your example, the car physically traversing Mexican soil IS the violation. Air tickets do not include contractual language disctating what you can and cannot do when you arrive after your outbound flight.
If you wish to participate in the carrier's attempts to artificially support and inflate their prices, you are welcome to do so.
I and all other smart travellers will travel freely on whichever flights and schedules I wish to until such time as some federal law mandates what any of us do upon arrival or where any of us must spend a certain number of nights.
