If it's Lyft Line, it automatically shows the destination, it's a faint grey line. To get the $5.00, you have to wait till the timer runs out, at that point it will pop up and tell you to call the pax. Twice I've had it do that, as soon as it detected I called the pax, it gave me another box allowing me to No Show the rider. Depending on where the pickup is, I'll call the pax when the timer hits 2:30 sec., because I realize pax, may not be paying attention. Especially if I think it's going to the airport. I had one recently that I called at 2:30, pax said she was coming, timer ran out, I called again she was trying to find her passport, I asked if she wanted me to cancel and she could rerequest, she said no, she tipped me $10 because I waited.
Depending, I'm getting between 225 and 260 miles to a tank of gas, keep in mind I'm only getting about 15 mpg around town. Although lately, if I behave myself, I've been able to stretch it to 16.5 mpg and filling at 1/4 tank, still getting around 250 miles. Obviously the more airports, the better mileage I get since I can set the cruise control.
