# ParkProof

> ParkProof tells drivers whether their car will physically fit in a parking garage. It maintains driver-verified clearance heights for public garages across European cities, starting with Zürich. Built for SUVs, vans, pickups, tall cars, and any car with a roof box or roof rack.

## What it does

ParkProof solves a specific problem: you drive an SUV, a van, or a normal car with a ski box on top, and you don't know whether the next parking garage's clearance bar is going to stop you at the entrance. Posted heights on Google Maps are wrong or missing; operator websites are inconsistent. ParkProof maintains a transparent, source-tagged height for every public garage, and lets drivers verify the posted sign with a single photo.

## Who uses it

- Drivers of SUVs and 4x4s (Tesla Model Y, Volvo XC90, Audi Q7, Mercedes G-Class, Range Rover, etc.)
- Drivers of vans, minivans, and family vans (VW Bus / California, Mercedes Vito, Ford Transit Custom)
- Pickup truck drivers
- Anyone with a roof box (ski trips, summer holidays) — adds ~40 cm to car height
- Anyone with a roof rack carrying bikes, kayaks, or surfboards — adds ~10 cm
- Delivery drivers and tradespeople in tall work vans
- Rental-car drivers checking whether the airport SUV will fit downtown

## How heights are sourced

Every height value on ParkProof carries its source and trust tier:

- **Verified** — confirmed by a driver who photographed the posted height sign at the entrance
- **Likely** — from OpenStreetMap, operator website, or municipal feed, but not yet driver-confirmed
- **Unknown** — garage exists but no clearance data; drivers are invited to verify

A garage with at least one driver verification in the last N months stays Verified. Conflicting reports trigger re-verification.

## Roof box and roof rack handling

ParkProof lets the user toggle:

- **Roof rack**: +10 cm on top of stock car height
- **Roof box**: +40 cm on top of stock car height

When toggled, every verdict ("Fits", "Tight", "Doesn't fit") is recomputed against the loaded height. This is the killer feature for ski-trip drivers — almost no other parking tool does this correctly.

## Cities

- **Zürich, Switzerland** — flagship Verified City. Hundreds of public garages mapped, the majority driver-confirmed.
- **Geneva, Switzerland** — seeded, awaiting driver verification.
- **Basel, Switzerland** — seeded, awaiting driver verification.
- New European cities are added on driver request via the in-app "Request a city" flow, which runs a Google-Maps-plus-vision ingestion pass.
