I hope that it is so, it took whole roll of duct tape and lot of waste cardboard, lucky me I don't throw anything away

Sadly one butterfly lost his life, first start to fly around here and this one hit my windshield, I could not see any change of it's erratic path to point from noticing to impact, that was under 2 seconds but more than 1 second. I remember reading from Aerocivic that bugs fly over the car and not impacting to windshield, but of course angle of windshield is different, don't know if I should even try to get air to run over the windshield.

There were also some very red birds on road, they seemed not to notice my car very early, had to steer to avoid hitting them when they did set to fly, I did observe clear bump to one, not a hit but air from front of my car kind of boosted the bird up, clear sudden lift as poor bird tried to escape flying to car's path, but still bit too low.

Usually birds fly off earlier, but this species was not the most common that I have seen, so probably it was just species not so used to cars.

I tested also on dusty road, dust behaves differently, I would say dust is now lifted up, bit mixed, but it is not like before where dust did spread all over the road, it is more controlled if one can say so.

Also I did notice that rear window is not getting much of dust or water spray as I did notice when there was wet section of road, water spray is really great for carboard body parts

Not very scientific, but I think they show that there was some change.

Back of car, underside is quite ugly in aero wise, there is car jack and spare wheel hanging from bottom of car, front of those is diesel tank and some other shapes that are not making surface really rough. I did eye that area and if I put some kind of plane there, it will be almost vertical, so that there is not much rise towards rear, this is perhaps good, was 4 degrees for that area some number to seek?

There is not going to be too much of decrease in diameter of car even I put all parts that I can, but I guess that if I can make air leave the vehicle cleanly that would be something worthwhile of effort.

Making such 'fins' as Volt has at rear has been on my mind all the time, maybe I try to create such to near rear lights.

I'm hoping of making kammback addon from clear plastic of some sort, there is 3rd brake light at top of rear window and I wish to leave it visible to other drivers, I think it was 20-30% less chance of being rearended if you have 3rd brake light.

Tomorrow I have 6 hour test drive, I hope to fill up after the drive to see changes immediately, also will be interesting to compare how much I can drive engine off, most of time I drive 50MPH but there are those slower speed areas which are mostly 37.3MPH they are usually very short ones. My average speed on that journey was 46.6MPH to there and back last week according to GPS, average speed is around there for all my trips really, I could go slower, but my trips are so long that I sacrifice bit fuel for time.
