Many people need a car to get to work, take care of their families, live their lives. But obtaining an auto loan can be difficult for those with a bad credit rating. Some finance companies are now willing extend credit to people who are poor risks. On one condition: the company can install on the car tracking software that has the ability to disable the ignition if the debtor misses a payment. This procedure has left drivers stranded oh highways and in dangerous neighborhoods. Is this practice unfair? Do the benefits of obtaining a loan outweigh the harm caused by this violation of privacy and loss of control?
