Back in the days before computers, auto insurance was personal and subjective. The insurance agent actually talked to the man he knew in the main office, called in a few favors, and got their best customers the best rates. Male drivers under 25 were charged a lot. Young females, being perceived as less risk, were charged much less.
Now, in the computer age, auto insurance companies have large databases of accident and claims records. By number-crunching these records they can tell what type of person is more likely to be a good driver and what type of person is more likely to be an accident risk. This Black Box technology gives them insights into the background and behavior of the people who they think should pay more for their auto insurance. For example, people who carry minimum limits of liability are actually a greater risk than those who carry at least 50/100 ($50,000 per person, $100,000 per accident). And statistics have shown that those with bad credit scores are more likely to be involved in accidents.
In Texas, the minimum liability limit on auto insurance is 20/40. Yep. $20,000 per person, $40,000 per accident. Not much is it? And if that weren’t...
