Not if the car is stopped. Here's how it should work:

1. park in a "drive-thru" stall
2. scan QR code specific to that stall (optional - connect to wifi at the stall)
3. enter order through a simple webapp
4. worker brings order out

If you want to talk to someone, walk inside, no need for a drive-thru window at all. That's basically how the old drive-ins worked, adjusted for modern tools.
