If I'm driving long distance on a road-trip, (approx. 400 miles, leaving house at 3am, arriving at approximately 9am) am I required to stop the car, get out, and daven Shacharit at or before sunrise? Is there a way I can daven while still driving? If I were to get an audio recording of a chazzan leading the service, say amen at the right points etc., would this count?
Those that I'm going with are not Jewish, so it'd be kind of awkward to tell them to wait in the car for an hour.
