On demand roadside assistance

Seems pretty cool! Last time I needed a tow, I Yelped tow truck services nearby, but none really had any reviews. Then turned to google search and went with the closest place I found. It took about 4 hours for someone to come. This has to be a better option than that.
This seems like it would come in handy if you're in a pinch, but also seems like people with AAA or Geico or another insurance co already have a solution to this problem (which to me sounds like a large part of the population). Wonder how big the market is for this.
