Uber has no business being in this group. They provide real value to customers and drivers. Taxis have provided absolute shit service in many places and Uber absolutely came in with a superior product and business.
Uber got where it did by losing vc money and by ignoring laws. That fits my personal definition of bullshit company.
If it is raining or the sun is out or the trains are busy or it is any of one a hundred random reasons - you will have surge pricing. Not just 10-15% extra but 100-150% extra. But don't worry keep standing around for a 30-40 minutes and checking the app eventually the price will come down...
