What if the other driver doesn't want to call police?
The request is common and it's usually explained sympathetically — they'll pay cash, they don't want their rates to go up, they're in a hurry.
The reasons people actually avoid police at a crash scene tend to be: no insurance, a suspended license, an outstanding warrant, impairment, or an intention to dispute what happened later.
Every one of those is something you want on a record rather than resolved with a handshake.
What goes wrong without a report. The promise to pay evaporates. The account changes. The other driver's insurer denies the claim because there's no documentation. And you discover weeks later, when an injury surfaces, that you have no proof the crash happened at all.
If they leave before police arrive, that's a different situation — get the plate, photograph the vehicle, and report it.
You're entitled to call regardless of what the other driver prefers, and you don't need their agreement.
Their reason for not wanting police is usually the reason you should call. ---
