How should drivers pick their comprehensive insurance deductible?

Pick a large number and save the difference. There is no one for someone to have a $500 deductible when you can have a $1k and save the difference. Price your insurance with both umbers, see how much cheaper it is with a 1k and save the difference into a savings account. As long as you can afford the deductible in a case of an accident, you are most likely better. The probability of you having an accident (and having to pay the deductible) is most likely smaller than the savings you will accumulate. The key is to make sure you actually save the difference and have $1k available in case of an accident.
