You should accomplish the above in your next six trips when you travel at 75mph. You'll have the analog equivalent of a roll of 35mm photos. And you only get one try per stop. If you get one really good photo out of the 36, you're doing well. And I know you will do well. You have to have the guts to post each of the 36 photos, though, six at a time, no more than a day or two after you make them.
OK - time for another gallery. I think you have to have some way of setting off a random alarm in your car, or maybe just set a variety of alarms that will go off at irregularly chosen times. You will give yourself the gift of 75 seconds, after you stop, to make a photo out of your car and start driving again, until the next alarm goes off and you have to do it again and again and again - at least five times - until you get home, where you have to make a final photo. No fair making the same photo from any stops, either, including you driveway.
