I only use Uber/Lyft in Boston for routes where the T would be inconvenient or if the weather is really bad and I don't want to walk home from the T station.

I just hate Uber Pool and Lyft Line - the routes they take are often side streets with lots of congestion and turns, there's a lot of frustration when you're almost to your destination or to a major road and then the driver turns around to pick up another passenger. Drivers often play music I find annoying.
