The shots during the motorcycle races with the Speed Channel overlay were filmed at Mazda Raceway Laguna Seca in Monterrey, California. However, the scenes involving the actual actors took place at Willow Springs International Raceway near Rosamond, CA, more specifically, the Streets of Willow Circuit.
Channon Roe and David Boreanaz were both in Buffy the Vampire Slayer (1997). Roe plays the undead thug O'Toole that gets Xander in trouble in the Xander-oriented episode "The Zeppo" in season 3, while Angel (Boreanaz), Buffy, and the rest of the gang are busy saving the world yet again.
