Why do drivers drive away?

Why do you drivers drive away?

I ordered a Lyft today as I normally do to go home from work. I mentioned to my driver that "hey can you give me some time to get in & out of the car as I'm using crutches?"

My driver responds okay and I see he's like 1 street away and Lyft is telling me he's 1 minute away so i walk outside as it takes me like a few minutes to open the door at my work (it's not very Ada friendly)...

My driver proceeds to just drive away when it's showing that he's less than 30 seconds away?...

I stood outside for like 10-20 minutes as he kept making turns on the streets that are right beside me. I ended up cancelling this ride, but..Is this normal?? Is this because I'm using crutches?...
