ObjectType implementing InterfaceType doesn't end up in the schema

Consider this code:

const {
  GraphQLID,
  GraphQLInterfaceType,
  GraphQLNonNull,
  GraphQLObjectType,
  GraphQLSchema,
  printSchema,
} = require('graphql')

const NodeType = new GraphQLInterfaceType({
  name: 'Node',
  fields: {
    id: {
      type: new GraphQLNonNull(GraphQLID),
    },
  },
})

class Car {} // Kept brief for demo purpose

const CarType = new GraphQLObjectType({
  name: 'Car',
  interfaces: [NodeType],
  fields: {
    id: {
      type: new GraphQLNonNull(GraphQLID),
    },
  },
  isTypeOf: value => value instanceof Car,
})

const schema = new GraphQLSchema({
  query: new GraphQLObjectType({
    name: 'Query',
    fields: {
      node: {
        type: NodeType,
        args: {
          id: {
            type: new GraphQLNonNull(GraphQLID),
          },
        },
        resolve: () => new Car(),
      },
    },
  }),
})

console.log(printSchema(schema))

Which gives this output:

interface Node {
  id: ID!
}

type Query {
  node(id: ID!): Node
}

This is a very simplified demo of the problem I’m running in to. Cars (in this case) don’t have their own queries so they don’t end up in the schema even though you can query for them by the interface they implement.

How can I make them appear in the printed schema?

@CrocoDillon You need to write this:

const schema = new GraphQLSchema({
  types: [CarType],
  query: new GraphQLObjectType({
