If we lose electricity the gas pumps won't work. Unless you have to add oil to your lawnmower gas it can be used as gas for your car. You may need your wipers after the storm passes. You don't want to block your car in behind something else. Downed tree limbs cause flats.
Bikes are great for short trips when gas is in short supply.
Usually there is a red ball one pulls to disengage the gears and allow manual operation. You will need to know how to do this to get your car out of the garage after the storm is over if electricity is still off. If you don't know how, get a manual or ask a neighbor with a similar garage door. You don't want to have to go to a detached garage in the rain when you need it. Allow at least 2 gallons per person per day.
