Many people have gone outside to start the car, then go back inside while it warms up.
Back in 2000, a law was put into effect because so many cars were being stolen that way.
Now, remote starters are really popular and many just press a button from inside their house and it starts. The only problem with this mechanism is the law hasn't changed.
Kenny Arnett, who owns a remote starter and installs them for a living, says he can't understand how advanced technology almost got him a ticket.
But, there are many ways the Kentucky law which prohibits a driver from leaving a car running unattended can be interpreted.
Arnett says he installed nearly 300 remote starters in the last year. That's why the policing of the law has become much more difficult, and some car makers are even offering the option.
The law was originally put into place for those that left their car running in the house or in the store and left it unlocked.
However, with remote starters, the doors remain locked and if someone gets inside and hits the brake, the engine would shut off and you couldn't go anywhere.
Arnett says the manufacturers of the remote starters need to provide a sticker to put in the window so police know it is locked, while unattended.
Many officers across central Kentucky say remote starters have made it more difficult to tell if cars have been left unattended or remote started.
Yet police do say they would not issue a ticket if they discovered the car was started with a remote and remained locked.
