Opened 5/30/2026
A moderate-energy left-turn intersection collision with the defendant Lexus cited under CVC 21801(a) for an unsafe left turn pins 81% technical fault on the defendant. All three alleged injuries are biomechanically supported: cervical shear reached acute-herniation tolerance, rotational head loading crossed the elderly-scaled injury-onset band, and lumbar sprain-strain superimposed on Mr. Donald's documented degenerative spine herniated a compromised disc. Remaining risk is evidentiary - an out-of-tolerance energy balance and unconverted speed inputs the defense will probe.
Factor Breakdown
Analysis Dimensions
All three of Mr. Donald's alleged injuries - cervical herniation, mTBI, and lumbar herniation - were tagged consistent by the biomechanical analysis, a fully aligned causation posture across every claimed body region.
Mr. Donald's documented degenerative disc disease, spondylolisthesis, facet arthropathy, and migraine history establish a strong eggshell-plaintiff profile that lowers his effective tissue and head-injury tolerances.
The liability engine pinned 81% technical fault on the defendant Lexus under a pure comparative rule, anchored by a heavy-weight citation against the defendant for an unsafe left turn failing to yield.
The crash severity dimension is low, and the defense will frame a moderate longitudinal delta-V as insufficient for acute structural herniation absent the eggshell argument.
The speed engine's mass-ratio energy-balance check came back OUT OF TOLERANCE, flagging the delta-V pair as physically inconsistent with the mass ratio - the defense will argue the alleged impact severity is overstated.
Mr. Donald's V1 pre-impact speed rests on an approximate, claimed-approach cell that was not reconciled to the authoritative closing velocity, leaving the plaintiff's own speed input unsettled for the defense to contest.
Records — Pull and parse the Treatment Chart Review and the officer-issued citation list from the TCR. The Evidence Integrity report flags the TCR as unparsed and structured extraction as unpopulated, yet the liability engine already credits a heavy-weight CVC 21801(a) citation against the defendant. Loading the officer-issued citations from the TCR upgrades the in-product Liability engine from its current Moderate band (+15pp), converting the unsafe-left-turn fault narrative from a catalog default into documented, per-se aggravating evidence.
Discovery — Subpoena the 2014 Mercedes CLA250 EDR pre-crash trace. The speed engine is currently Weak with an out-of-tolerance energy balance and Mr. Donald's pre-impact speed resting on an unreconciled claimed-approach cell. The EDR pre-crash trace upgrades the Speed engine to Strong (+20pp confidence) and independently anchors his approach speed and brake-switch onset, simultaneously closing the energy-balance inconsistency and rebutting the defense argument that the alleged delta-V overstates impact severity.
Liability — Lock in the avoidance record by deposing Mr. Donald and witness Cristian Radu on time, distance, and signal state. The avoidance analysis returned avoidable_with_margin on his side based on a constant-friction model with no EDR-actual PRT available, which the defense will use to push comparative fault onto him. A dashcam timestamp or EDR brake-switch onset upgrades the Plaintiff avoidance engine to Strong (+20pp); pairing that with Radu's independent right-of-way corroboration neutralizes the avoidable-with-margin posture and reinforces the 81% defendant fault share.
