I had a long-term foster that did this as well. I did a lot of work to make rides fun, not stressful, just like the post above explained. It took a long time, I added length to the trips very gradually. We started with getting into the car and getting out immediately, then progressed to having the doors shut for a second, etc. - I never added more than 5-10 minutes to the trip at one time. It did help eventually. I also found these management techniques to be especially helpful for longer trips (some repeats from above):

1. Limit food/water consumption on day of long trips. An empty belly isn't good, but only a small snack at most.

2. Nice long walks before the trip, to make sure the dog is empty and tired.

3. Keep the window cracked a bit during the trip. The fresh air helps me when I'm feeling carsick, figured it couldn't hurt him.

4. Consider a non-edible toy for the trip, something to distract the dog from it's nervousness.

5. Keep the speeds and turns consistent. My husband had problems with this!

6. On longer trips, stop every 30 minutes for a 5-10 minute break. Get out, let the dog stretch and potty if necessary. It adds time to the trips, but I think it was REALLY important in avoiding vomiting.
