The Connecticut State Police Traffic Division, which has been running a group of unmarked Mustang LXs since 1984, recently purchased six sporty, two-door Mazda MX-6 GTs. These Mazdas are replacing some of the older Mustangs. Mustangs have been used around the country long enough now that some traffic officers say they are no longer necessary because there are other cars that can be handled more safely during high-speed pursuits. The California Highway Patrol, known for its innovations, is now testing a Toyota Camry sedan for possible use as a new lightweight cruiser. There are currently no plans to replace the Mustangs or Chevrolet and Dodge sedans used now, but there is concern that the large gas-guzzling rear-wheel drive cars will disappear in the future. In fact, fuel efficiency is one major reason that traffic enforcement agencies are replacing their old cars. Other reasons include the ability of the newer cars to reach a higher speed sooner than the older cars, and the availability of safety features such as air bags and four-wheel disc brakes with anti-lock braking systems.
