I too feel the same but i feel i know why it is this way. At nights the roads are pretty dark at the first place and its very calm inside the cabin which after some times makes the brain activity weak, airconditioner even worsens the situation, iam sure the people who are facing problem are running the car with airconditoner ON. The few old cars airconditioner produces small percentages of carbon monoxide which actually makes the person driving car drowsy, i would recemmond to roll down your windows atleast for 5 mins for every 30 or 40 mins of drive to take fresh air which you can clearly see the results and try to avoid to see opposite headlights directly, hope this helps.
I too suffered from many of the same symptoms outlined in so many of the posts. Over a year later, I'm able to drive without too much distress and dizziness. While it is not perfect, I am no longer petrified of driving. I'll give more of my details and bio at the bottom of the post, but here are the actions that I took to improve my case:
1) I underwent Balance Retraining Therapy. This involved a number of tests and therapies, but the one that produced the best results was an exercise where I looked at a letter, about 2 inches high, placed at eye level on the wall 4 feet in front of me. Then, I moved my head back and forth about once per second for 15 seconds, then up and down for 15 seconds at the same cadence, and finally back and forth for 15 more seconds all the time while focusing on the letter on the wall trying to keep the letter stationary. I did this for about 3 days. After 3 days, I performed this action twice per day, the second time the pace was quickened and the head didn't move as far. Similar to if you shook your head to indicate "no". Performing this action more than this does not help, in fact it can hurt. I saw a huge improvement after 3 day.
2) I started allergy shots. I was having problems with seasonal allergies that resulted in sinus drainage. This has helped a little.
3) I use a steroid nose spray before bedtime during the times of the year when pollens are at their worst and I experience significant sinus drainage. This too has helped some.
All of my hearing and inner ear testing came back as normal. No problems with blood sugar, pressure or any other test. It wasn't until I took the balance tests where I was moving my head back and forth while starring at the dot on the wall did it become clear that something was amiss. The dot was moving all over the place. As it was explained to me, balance problems can still go undetected even if the normal ear, nose, and throat hearing and balance tests are performed. This was my case where I passed all those tests without identifying any underlying problem.
The other point to note is that balance is a combination of sight, inner ear balance, and to some extent, touch. The "floating sensation" that you experience is a result of the brain unable to discern between what your eyes see and your inner ear detects from a balance standpoint. As it was explained to me, when the brain cannot discern what is going on, it gives you that "dizzy feeling" because it can't figure out which input is correct. The balance retraining therapy is to get the inner ear back in sync with what the eyes are seeing, thereby bringing the two into sync.
Just a short bio: My problem manifested itself when I was 52 years old, although I had on and off problems before, usually when I was suffering from allergies. I'm a male in good health.I underwent all the testing through my ear, nose and throat doctor. Like most of you, explaining this problem made me sound like I was nuts. It occurred worse when I was driving on a multi-lane highway with barriers on each side faster than 50 mph. There were occasions when I was very tired, the problem occurred at speeds as low as 35 mph. One side-effect is that I have a tendency to experience anticipatory anxiety. That's what I'm battling now. The way that I have worked through this problem is by driving on multi-lane highways when I'm feeling my best. This reinforces (in my mind) that I can drive on these roads and be relaxed while I drive. After 1 year, I'm just about over this problem, but I still have bad days due to sinus problems or occasional anticipatory anxiety where I think too much about the road where I've experience the problem in the past. It is tough to forget those roadways where I've become dizzy and then experience an anxiety attack so bad that I could barely drive off the highway because I was violently shaking.
I hope that maybe my experience can help those of you who still suffer from this problem. There is help. Search for "Balance Retraining Therapy" for a location in your area to see if they can help. Determine if there is a correlation between sinus problems and days where the problem is worse. Possibly a combination therapy will work for you too. Best of luck!
Hello all, as mentioned above, there is another post/thread on this topic and within the past 24 hours I have requested anyone who is still suffering from these similar symptoms to please let me know who you are. Once I have an idea of how many still are, I will post the steps to give relief to some or all of you. I will have a few questions to ask such as current medications and such, so please feel free to join me over here:

I've had this problem too I go to the dr in march. I also feel like my head will explode when I stand up at times
I feel the same exact way and I am also a diabetic.
Hi folks, I was driving home tonight on a 2.5 hour stretch and suddenly felt a "disequilibrium." I have had similar symptoms for years but it was intermittent so it is hard to trace. At first I thought it might have been some food I ate. Then I thought maybe it was the air conditioner. So I pulled over on the next exit and parked for 15 minutes and tried to breath deeply. As I drove home, it occurred to me that I was experiencing a LOSS OF DEPTH PERCEPTION (esp. since this "vertigo" occurs mostly at night, but not exclusively). I was able to re-train my eyes to look at signs in the distance and tracking them as they approach, then focusing on the next sign, and so on. In this way I was able to continue driving despite the "disequilibrium" I experienced. I hope this may be of help to someone next time they run into a similar experience!
Best regards.
