You're right on this logi... it'll cost more in the short run to pay for another 'potential driver' in the family but in the long run paying for an accident and an injury out of pocket would be a disaster. This guy's lucky the cost is ONLY $5,000. Throw in a small injury and it could have been $30,000
Had he hit a static utility box or pole, the bill could have cost him dearly ($80-200K or more).
