let's ask alison chantelle, she profiled the company as a senior reporter. i use uber often, but when i think i won't get a taxi, because it's more expensive. i can't imagine the demand is really shunting demand for cab drivers aside. why are they so angry? >> part of the reason they are angry is that uber operates above the law. a lot of times they do. they ask for forgiveness more than permission and they come to cities despite regulations being in place. it makes cab drivers mad, because they had to get licences and uber drivers are coming in, turning on the technology and picking people up. >> i understand the difference between them and a taxi driver, we have limo services throughout the country, black car services. is uber fitting more that model? >> that is how it started. it's expanding into a competitor with taxi. they have uber taxi working with the cab company, and uber x. you and i could run to the scpar pick people up. they have lowers and uppers, black car like you talk about. >> you have variety. wouldn't they be regulated in the same way? >>
