JQ JSON parser, concatenate a certain child of an array

Question

I have the following JSON input. The array is called cars. So if I do .cars I get what you see below.

Now I have to concatenate all .name elements for each item of the array. I want the output to be

Audi
VW
Audi,Honda,Chevy

Can you please help me construct the filter to output this concatenation of .name? Sometimes .name can be empty, not null, nothing just empty. So I do need a // "null" added to the filter as well. Thank you in advance.

[
  {
    "self": "link",
    "id": "18900",
    "name": "Audi",
    "releaseDate": "2015-12-11"
  }
]
[
  {
    "self": "link",
    "id": "18900",
    "name": "VW",
    "releaseDate": "2015-12-11"
  }
]
[
  {
    "self": "link",
    "id": "19400",
    "name": "Audi",
    "releaseDate": "2015-11-20"
  },
  {
    "self": "link",
    "id": "18900",
    "name": "Honda",
    "releaseDate": "2015-12-11"
  },
  {
    "self": "link",
    "id": "19201",
    "name": "Chevy",
    "releaseDate": "2016-01-08"
  }
]

.cars | map(.name? // empty) | join(",")
