See, I find part of what you're saying compelling, but I don't have the slightest problem with that question, specifically--with her mental state. She's been through more trauma in, like, four years, than most people would go through in 40 lifetimes. She's been in love with multiple serial killers, almost been killed a few times, fell in love (not just love...she's in love, right now, which makes a lot of crazy stuff instantly plausible) with her brother, found out he was a killer that same day, found out her father (who she worshipped) was keeping a secret from her, came around to her brother-killer's philosophy, finally asked him to kill someone, and instead he fell in love with that other person instead of her. Like, wow. She's got an entire airport's worth of emotional baggage.
They've laid tons of groundwork for this. The entire season has been Dex slowly persuading her that things like this are okay. This is the exact ends-justify-the-means kind of thing he does all the time. She literally just finished helping him plant evidence before it happened. The entire narrative arc this year has been Deb slowly becoming comfortable with more and more deceptive, extra-legal dealings if the end result is getting rid of a killer.
I struggle a little with whether or not she'd actually crash her car (though again, the idea there is that she simply misjudges the severity, not that she almost killed herself on purpose), but I don't struggle at all with the idea that this is a plausible mental state for her to be in.
