Why should they exit a car over a speeding ticket? A speeding ticket is not a jail sentence and does not warrant an arrest. In fact unless a driver is actively trying to harm somebody or has an active arrest warrant there is no reason whatsoever for them to leave their car or allow cops to remove people from cars.
In some states, it is the law that officers can order you to step out of the vehicle during any valid traffic stop, regardless if it is criminal or civil.
In some states it is the law that if you are from out of state and get a speeding ticket, you either have to pay the officer in cash while you are stopped or they can take you to jail until money is posted or it is your court date.
This happened to a friend of mine from Wisconsin, visiting me in Michigan about ten years ago. I was shocked to learn this was actual Mochigan law, and could hardly believe it even after verifying it. He felt very “lucky” to have had several hundred dollars in cash to simply hand over to the officer. Michigan only just rescinded those laws in 2019: https://landline.media/michigan-laws-end-roadside-cash-payme...
It's actually great. Their tickets are (or were) cheap and not reported to insurance if paid on the spot.
Far superior to the "pretend it's more than 1% about safety and peddle it to the worst kind of people" approach that most other states take with speeding enforcement IMO.
In the sovereign citizen cases they are talking about, the typical case is that the vehicle is not registered/doesn't have plates and the driver refuses to identify themselves. They only barely lower the window if at all. They usually go back and forth a few times until the police tell them they are under arrest for multiple reasons relating to driving without a license and failure to identify.
The glass breaking happens after multiple offices have arrived for backup as the person usually gets dragged from the car screaming. The videos are extremely entertaining to watch.
The combination of unregistered vehicle, failure to prove the driver has a license, and the drivers insisting they should be allowed to drive away is absolutely a combination where arrest is legal.
You don't necessarily have to if you're just getting a speeding ticket. But in order to write a speeding ticket, you have to hand over a valid Driver's License so they know who to ticket. Exactly what should they do if the driver refuses to provide their Driver's License?
