4- Look into getting a power pack, some have compressors (for flat tires) and you'll never need a 2nd vehicle to jump start your own.

Frank, let me offer a little tip about these cheap air compressors. On a flat tire, they will inflate it...........eventually, and usually gets red hot in so doing.
To assist this little fella, jack up the car to get the tire free from the pavement. It will inflate much easier and puts much less stress on the compressor by not having to raise the vehicle in the process. However, by their very nature, all air compressors heat up to some degree.
