I'll vote 'don't also.
The lowest pressure outside the vehicle is near the windshield.If you open the sunroof and rear glass,the low pressure above the roof will telegraph through the cabin,bringing air and exhaust fumes forward towards that low pressure as it attempts to equalize the static pressure between the two areas.
It not only ruins the airflow,but it poisons you to boot!
