Uber costs are different in different areas. I suspect the areas with higher minimum wage also tend to correlates with higher rates for Uber due to a higher median income, enabling a higher optimal price on the price:demand curve. A random website and some very nonscientific sampling (internet forum stats at their finest!) seems to provide some confirmation of this hypothesis:

http://uberestimate.com/prices/Seattle/ - $1.35 base, $0.24/minute, $1.35/mile, $1.95 service fee, $5.45 minimum fare

http://uberestimate.com/prices/Miami/ - $0.95 base, $0.13/minute, $0.91/mile, $2.20 service fee, $5.50 minimum fare
