How do I buy a totaled car from an insurance company?

I filled my coolant less than a year ago, but my car’s thermometer is showing crazy high readings. Should I add more coolant? How often do you need to fill coolant?

I’m trying to think of creative ways to save on gas money. If I drove everywhere with a half-empty tank, I know that my car would be lighter, and that would increase its gas mileage. Say I was able to drive with seven fewer gallons of gas in my tank (on average)—how much weight would that remove from my car? How much does gasoline weigh per gallon?

How far will GEICO tow our SUV if we get stuck one day? My partner added GEICO's roadside assistance to our policy. The price is so cheap that I feel like it can't cover much.
