Armed carjackings are on the rise in many major urban areas. I happen to live in the greater St. Louis MO metro area where it has become an increasing problem. Most perpetrators are young males, many as young as 13 to 14 years old.
According to multiple articles I’ve read, the increase of carjacking of victims as they are getting into or out of their cars is at least partly due to technology. Many cars now will not function without the key fob nearby, so old fashioned hot wiring doesn’t work on those cars. So carjackers need to grab a car along with the keys, hence armed holdups of victims. Even more alarming is the increase in victims being shot despite immediately complying with handing over keys, phones, wallets, purses.
Some of the stolen cars are used for other crimes. Some appear to be used for joyriding and fairly quickly dumped.
This is an entirely different issue than parked vehicles being broken into.
