DETROIT (AP) When they pull up to a gas station, Detroit drivers are looking beyond the price per gallon at a far more threatening concern: carjackers.

The armed auto thieves have become so common here that parts of the bankrupt metropolis are referred to as "Carjack City," and many motorists fear getting out of their vehicles even for a few moments to fill a tank.

So gas stations are taking steps to protect customers, and the city has formed a special police team to go after carjackers.

Authorities blame many of the carjackings on improvements in vehicle security. Anti-theft equipment, GPS systems and advanced locks now prevent many vehicles from being driven without a key in the ignition. That makes it hard to steal parked cars. Instead, thieves target occupied vehicles.
