I wonder what the ettiquite is when sharing a ride like this? On a bus or in a cab there is no pressure to make conversation with the other passenger/driver, although sometimes they may be chatty. In this situation I'd feel pressure to make conversation with the driver, but what if I want to just read? Would that be rude?

If I found a good driver I would just deal directly with them because (a) I know they share my route and (b) I don't need to get to know them again each time I commute. That would be money off the table for Lyft though.

But I would not use the service because I have kids to drop off and also I may not finish at the same time every day.
