They don’t call them “millennial anti-theft devices” for nothing.

Maryland police said a strong-arm carjacking was reportedly thwarted one weekend because the alleged thieves were sorely lacking one critical skill necessary to pull off the heist: the ability to drive a stick shift. According to the Montgomery County Department of Police – Major Crimes Division, the incident happened on a Saturday evening at a gas station in Germantown, MD. According to their report, a man had just finished pumping gas and was getting into his car when two male teens ran toward him.

“The juveniles forced the door open, grabbed ahold of the victim and demanded his keys,” the report said. “The victim complied with the juveniles’ demands.” But from that point on, the encounter didn’t exactly go off as planned.

“The juveniles entered the victim’s car and attempted to drive away.” The key word there is “attempted.”

There’s video footage showing some movement taking place by the carjackers, but as the seconds ticked by, the car refused to budge. Eventually, the uninvited guests came to the realization that they were running out of time and were not going to be able to start the car.

“Unable to drive a manual transmission, the juveniles exited the vehicle and left the scene on foot,” the police reported. A few minutes later, officers saw two juveniles near the scene of the crime.

“When officers attempted to apprehend them, they fled on foot. After a brief foot chase, the juveniles were quickly apprehended,” according to the report.

Officers detained a 16-year-old from Rockville and a 17-year-old from Washington, D.C.

“Both juveniles were arrested and transported to the Montgomery County Central Processing unit, where they were charged as adults, with one count of carjacking and one count of conspiracy carjacking. They are currently being held without bond,” the report concluded.
