Let's look at it from a different perspective. Usually (and I hope this isn't a gross simplification or distortion) people look at "motive" and "opportunity" for foul play/criminal activity.
In general
Opportunity: unclear. He left at 11 p.m., not even his parents know (with certainty) that he would be showing up after midnight. He had driven less than thirty minutes before his "digital trail" disappeared. He did open the Snapchat app which turned off his Waze, so there might be something there.
Motive: None known/clear. Nothing of JL's valuables are missing - his gaming gear was all there, his phone was stuck in the car, nobody had took the marijuana either (if there is a third party involved).
Jason met foul play in Luling idea:
Opportunity: He was in Luling for less than five minutes...again, i keep coming back to whether he was in contact with someone on Snapchat at the time, a meetup of some kind.
Motive: Again, none that I can think of. No financial/valuables missing. Someone suggested earlier that KL being an attorney could have made him a target. Again, I doubt that because it serves neither purpose to make him seem possibly alive (so no kidnap motive). If it's to "send a message," again, there is no body, it does not serve as "deterrence."
It also strains credulity that whoever harmed him in Luling would have taken the car and crashed it on SFR. From an earlier post, it's a bumpy, rickety dirt road, can't drive fast (the wording was that if he was being chased down SFR he'd have a flat/blowout long before the accident site). Someone would have taken another road to take the car wherever if that was part of a plan.
Jason tried to start a new life.
Opportunity: again we veer off into possibly unknown third parties and descend into 100% speculation.
Motive: I highly doubt (though not impossible) to imagine someone going off without phone, backpack, or beta fish.
While the single car accident/wandered off theory has a lot of holes, doesn't make a lot of sense, and has a lot of questions, I find any other theory (as of right now) to make even less sense.
