Santa Fe Hybrid - NO SPARE TIRE? Is this a problem?

I'm surprised the Santa Fe has no spare tire... has some "kit" (how does that work?). the sales person said "most people use Hyundai roadside assistance (Does that come with the car?) I rarely get a flat but what happens if I do and I'm not near a Hyndai dealer? Was this a concern for you? I understand that it's heavy and there was no room for one...but I'm a little concerned. thank you
