What happens if something you do (accident or mechanical failure, unforeseen circumstances), starts a fire that burns down 1 or 2 houses? Then what? 
It's your call, just making you think about it. Ultimately it's your choice what kind of coverage you want. I don't know many people who have such a... robust policy as I have.
I'll take my chances with the whole burning down houses stuff. But I was quoted $115/month from progressive with:
Bodily injury and property damage:30/60/25
Uninsured/under insured motorists (lots of them in Texas): 30/60/25
Medical payments: 10,000/person
And $500 comprehensive deductibles, and that's it. Anything else I need or don't need?
