Low mileage drivers already save loads of money with Just Insure, as you are only paying for the few miles you drive each week, plus a small daily cost. There is no cost for when you are sleeping or working virtually from home, or gardening or just hanging out.
An additional opportunity to save more money would be to consider dropping any Uninsured or Underinsured coverages on your policy, which would reduce your per-mile and small daily cost even more.
