Our Siberian Husky is a great car traveler. When he is in the car he wears a harness that is secured using a seat belt connector in the back seat. He loves to have his head out the window on short trips (it brings a smile to pedestrians and other drivers). On the longer trips or when we are on the motor way we close up the window and after about ten minutes of looking around the dog usually curls up in the back seat and snoozes for up to two hours (we try and give him a walk beforehand to help relax him for the trip). We usually stop at motorway stops or petrol stations and give him some water and a walk around for 10-15 minutes after an hour or two of travel. We have taken him around the country on car trips of up to 6 hours in duration (it adds less than an hour to the trip). He usually needs to stretch his legs after a long trip. Of course, that's our experience and this may not be the case for other Huskys.
