One thing that Lyft does and Uber does not do is Lyft requires both drivers and passengers to log in with their facebook account.
Required Facebook membership? No thanks.
Lyft could do some interesting analysis to match people up based on shared characteristics.
These people need to get out of their comfort zone. Expose them to different cultures and ideas. Using FacEbook to ghetto-ize drivers is xenophobic. No sympathy for the OP complaining about immigrant drivers, either.
