Cars that unlock without pressing anything or by pressing a button on the door look for the key that is bound to them. It is secure in that only a key programmed to the car can tell the car it is ok to unlock. They keys are authenticated with a rolling code that is synced between a car and key when the key is programmed to the car. Thieves clone the key's signal and then the car has no idea that the fake key is not the real key.
You can't hotwire a modern car. On a modern pushbutton ignition car the starting function is allowed through a security module that makes sure the key is there before starting. Pushing the button only asks permission to start the car and then the module is the one that tells the car to start.
Lock-picking a modern car can be done, but it is far easier to use a wedge and inflatable air bag to pry the door open enough to use a hooked tool to open the door from the inside. Nobody picks automotive locks anymore, a lot of the door locks can be ripped out and bypassed anyways. You can of course just break the glass, but it may sound an alarm. The F150 has a massive theft issue Ford won't bother to address, the alarm can be disabled from outside the car using no tools whatsoever.
Once a thief has access to the inside of the car, they can program a new fake key using specialized software which is usually dealer level software but it can be done using 3rd party software. You can't just ban all non-dealers from having the capability to reprogram keys, that is user-repair hostile and would mean you have to pay whatever the dealer wants to replace a lost or damaged key. Not to mention that thieves will still find a way to access dealer tools and keep on stealing anyways.
A lockout period wouldn't accomplish anything, the original key still gets cloned and can be used to drive the car away. Once the stolen car is taken, the thieves have all the time they want to reprogram a key.
Enhancing security measures by using a more secure key authentication method will only go so far as to preventing theft and will add considerable costs to cars and key replacement. Thieves will catch up to any means of securing cars. A better solution is to improve economic prospects and enforce the current laws effectively to remove incentive to steal cars.
Your points are all valid and I agree with your suggestions. I still think every hour of delay is important to try to track down the car before it gets out of the country...
So compare an easy to steal car with a keyed ignition, with a modern push to start car. I don't drive now but I used to drive the former. It wouldn't sell for much in a used market or criminal market. Being stolen for use in a crime it may be more useful on the other hand. I don't know if thieves looking for easy marks would go for that car over one with more modern tech...
Auto theft for sale in a foreign market or domestic is uncommon and mostly dealing with valuable or rare cars and typically happens within a gas tank of a international boarder. More common is for breaking down and selling parts, but that is still not that typical. Most auto theft is for personal use and to commit crime. The breakdown of types of thefts changes with area, so in America personal use or crime is more common than Europe where chopping or foreign sale is more common.
Most turn-key ignition cars can't be hotwired either, they have immobilizers that require a security chip authentication within the key. Most of the cars that can be hotwired are from before 2005, after that they get rarer. If it has an all metal key, those definitely can be hotwired.
When it comes to tracking, by the time the car is located it is done being used. Most cars do not have any form of tracking that is accessible to law enforcement with cooperation from manufacturers. Modern cars with tracking can have their GPS or cell network disabled by pulling the right fuse with no impact on the drivability of the car. Aftermarket trackers are harder to disable if they are installed correctly and can lead to a faster recovery if the police move fast enough. Once the car is taken and the GPS fuse is pulled, they can keep the car indefinitely without fear of getting caught via tracking. If an aftermarket tracker is used, they just need to have the car in a place that will block the signal for long enough to disable it and then move the car again fast enough. Cops move slow, you can tell the cops where it is right now and they may not attempt recovery for hours.
Since the majority of auto theft is just looking for a car to ditch, in America, the easier to steal the better and it doesn't matter what the car is. F150s and Kia/Hyundai are the most popular now because they are easy to steal and common as dirt but grabbing a 2022 Honda that is left running or grabbing the keys from a driver are popular options.
