Before I start, let me explain that these type of devices are new to me. The Passtime company which is based in the United States has shut down the car of a Female driver while she was on the highway in Las Vegas Interstate. This incident happened in 2012, but the dailymail.co.uk reported on it in 2014. The female was driving the car which she got from her auto lender, but once she missed a payment, the auto lender initiated a shutdown procedure which disabled the car of the female driver.
As you can imagine, the female driver was shocked and was unable to control the car any further, this resulted in a near crash on the busy interstate.
But it is not the first time, the dailymail reports that this case has happened before with auto lenders which use the PassTime (Ontime) device to track and control their cars.
