People want to know what a big thing is. And this has been an evolution of combining online and mobile and the retail store experience into one seamless operation. There is absolutely no question that we live in a multichannel world and all of those areas have converged dramatically and the customer wants what he wants when he wants it and the way they want it delivered.

On the other hand the alternative was to wait in the rain and not have a taxicab. Dynamic pricing is here to stay, i think. They need to do a better job of letting the passengers and consumers know about it, but i think it is good going forward. Lynn drop in next time you are in town, well have this conversation in person. Good to be with you ali. My final thoughts are for drivers struggling in driving in so many parts of the country. I got one response from a viewer tell me about a personal experience in which he rear ended a car in a parking lot. He thought about paying it, but decided to run it through the insurance. A passenger later claimed to have whiplash from the accident, now by having reported that relatively small claim to his ininsurer, that viewer was covered.
