Other driver's insurance says I'm 30% at fault for a crash that was clearly not my fault??

"Shared-use traffic area" is absolutely an adjuster talking point designed to muddy the water and reduce the payout. They use vague language like that specifically because most people don't push back. Don't accept it as gospel — it's a negotiating tactic, not a legal ruling.

Stop calling. Put everything in writing from here on out. Email the adjuster, CC the supervisor, attach the video file or a link to it, and state clearly that you dispute the 30% fault assignment and that the footage contradicts it. Give them a deadline — say 10 business days — to respond with a revised determination. Paper trails matter. If they still stonewall you, talk to a lawyer.

Are you doing okay physically? A lot of people brush off soreness after a low-speed collision and then realize weeks later there's something going on with their neck or back. If you haven't been checked out yet, please go — even urgent care. And if you have any symptoms at all, make sure that's documented in your claim. The stress of all this insurance back-and-forth is real too, don't forget to take care of yourself through this.

I used to work on the claims side and I'll be real with you: when an adjuster assigns comparative fault in a parking lot scenario, it's often a starting position, not a final verdict. They count on the claimant getting tired and accepting the reduced offer. The fact that you have video is huge — most people don't. Make sure you've submitted that footage formally in writing (email, not just a phone call) so it's in the claim file. If it gets ignored after that, you have documented proof they disregarded clear evidence.

Quick question — when you submitted the video, did you send it directly to the adjuster or just mention that it exists? There's a big difference. And did you get the police report? Sometimes the way fault is described (or not described) on the report affects how the adjuster frames things. Just want to make sure all your evidence is actually in front of the right people before assuming bad faith.

The fact that you have that footage puts you in a WAY stronger position than most people in this situation. Seriously, most parking lot disputes come down to he-said-she-said and insurers know it. You have actual video. That's not nothing — that's probably your whole case right there once the right people see it.

Not legal advice, but parking lot fault disputes with video evidence are actually pretty common territory for personal injury attorneys. Most offer free consultations and work on contingency, so there's no upfront cost to at least hear what your options are. The video you have is genuinely valuable — don't let them bury it in a file somewhere.
