Issue with Laravel Migrations and Foreign Keys

I am currently receiving the following error when I run my migrations:

SQLSTATE[HY000]: General error: 1005 Can't create table 'saferides.#sql-189_4bc' (errno: 150) (SQL: alter table `rides` add constraint rides_car_id_foreign foreign key (`car_id`) references `car` (`id`) on delete cascade)

After reading a lot of issues about errors of this nature in Laravel, I have done the following to avoid it:

• Not reference a primary key with a foreign key until the primary key is created ( I make sure of this by keeping my table creations and foreign key assignments in separate migrations in the following order creation -> keys
• Make sure the primary key and the foreign key are of the same type (unsigned int(10))
• Explicitly state the storage engine to be InnoDB

Currently, I have my migrations set up so that the tables are created first:

// Up function for cars table
public function up()
{
    Schema::create('cars', function(Blueprint $table)
    {
        // Explicitly state storage engine
        $table->engine = 'InnoDB';

        // Primary Key
        $table->increments('id')->unsigned();

        // Other columns
        $table->string('car_num');
        $table->string('available_seats');
    });
}

Then my next table...

// Up function for rides table
public function up()
{
    Schema::create('rides', function(Blueprint $table)
    {
        // Explicitly state storage engine
        $table->engine = 'InnoDB';

        // Primary Key
        $table->increments('id')->unsigned();

        // Other columns
        $table->boolean('completed')->default(0);
        $table->boolean('no_show')->default(0);

        // Indexes to foreign keys
        $table->integer('car_id')->unsigned()->index();
   });
}

After all my tables are created, I add my foreign keys to the tables.

public function up()
{
    Schema::table('rides', function(Blueprint $table) 
    {
        $table->foreign('car_id')
              ->references('id')->on('car')
              ->onDelete('cascade');
    });
}

Any advice on how to fix this would be appreciated.
