Im definitely not making excuses for JLM and in fact have zero sympathy for him at all but I agree with the assessment about his maturity level.
The condition of Jesses car, the expired inspection sticker, his numerous garnishments, his living situation, the likelihood that he has very little money yet is a regular at local bars and his working what is basically an entry level job, his speeding away from police, getting into numerous fights, poor impulse control, anger management issues, all of that, taken as a whole, is not what a person would typically expect from a middle-aged 33 year old man.
Maybe a person in their late teens or early 20s.No offense intended as Im sure many of them are much more mature than him........ which kind of illustrates my point.
