From the album Daughter from Hell
She's narrating her own denial in real time. The car metaphor runs through the whole song, but it's backward, she thinks she's asking to keep driving when what she's actually describing is the crash already happening. By the bridge, she's doing forensic analysis on a relationship that ended before she admitted it started ending.
Do you hear the sound / Of our engine fading? / Really ran it out / Four tires flaming, can't we just hose 'em down?
The engine is already dead and the tires are on fire, but she's proposing a garden hose as the fix. That gap between the scale of the disaster and the scale of her solution is the whole song in four lines.
You floor it, I choke when you find the ground
This is maybe the best thing she's written. 'Finding the ground' should mean landing safely, but here it means he's grounding her, stopping her ability to breathe. The grammar makes his escape her suffocation.
Tell me where you've landed / Don't you thank me now / For my understanding / There's none of that, close your mouth
She tells him not to thank her for understanding, then immediately says there's no understanding and shuts him down. She's arguing with a response he hasn't given, which means she's arguing with herself.
I believed every word that you read / Every glorified tome by the side of your bed / When you swore you'd go right / Then you went left instead / How was I supposed to know?
She trusted the books he read like they were his values, which is a completely unhinged way to know someone. That detail makes her 'How was I supposed to know?' land differently, maybe she wasn't supposed to know because she was reading him through proxies instead of listening.
I would've fought anybody / Who tried to tell me you wanted out / Beat to a pulp, 'til I'm bloody / Oh, God, you can bet, I regret it now
People did try to tell her. That conditional 'would've fought' becomes past tense by the second line, she did fight them, and now she's admitting they were right. The violence she imagined using to defend him, she actually used to defend her own denial.
The song never tells you what he actually did wrong, only what she did to herself trying to make it work. That absence is the point. She was so busy accommodating that she missed the part where he stopped wanting to be accommodated. What sticks is that question in the bridge, 'How was I supposed to know?', when the answer might be that she already did.
