For the price of one roadside jump you can pick up a portable jump starter, compressor and inverter at Amazon/Pep Boys. Something like this:

You'll never be stranded with a dead battery again, can inflate flat tires wherever you are, and can charge your cell phone if your battery can't be revived. I bought one years ago after dealing with a bad alternator and keep it in the trunk of my car; so much peace of mind. You even get to be a hero, jumping other peoples' stranded cars without needing cables or risking your own car.

That is pretty awesome. Although getting an Uber X to jumpstart you only costs $8, but for the peace of mind and range of coverage, the $75 is probably worth it.

Id say the 75 was the better choice here... jump it 10 times and its paid for itself. Plus no waiting AT ALL! So explain to me how it would be smarter to call a cab if you know you have alt issues?
