As many know the monument used to be a great place to drive at night. with no traffic and relitivly safe conditions it was a lot of fun. now there is so much enforcement by park rangers that it is dangerous. I live in Glade Park so I drive the road every day. Many common spots are the Devils Kitchen parking lot 0.1 miles past the guard station. and Cold Shivers parking lot near the top at about 3 miles. Watch for parking lights and keep your speed reasonable.
