CMV: There is no purpose to rating the Door Dash Delivery driver.

So I'm new to using Door Dash and it is possible I don't understand the purpose of this feature. But I noticed that you can give the driver stars for performance. However,  I don't see any purpose to rating the driver:

1. I cannot choose a prefer driver. 
2. I cannot choose a driver after the order has been submitted.
3. When I'm choosing a tip, it doesn't tell me which driver it will be for. So I don't know if I should change my tip based on level of service. 
4. I cannot give a tip AFTER the food has been delivered. 

So overall, I seems to be a useless feature of the app. Please CMV!

It's so they know which Door Dash Delivery drivers are doing their job and which ones aren't. If the drivers score goes below a certain level they will get dropped from the system.

TLDR

It's not for you, it's for the system.
