My ears are ready to ear you...
I looked at thick tape this afternoon, but couldn't find some

Yeah, a CRV is bigger than you might think. (Heavy too).
Yes, that's the article.
"Four AirTab vortex generators were placed at the leading edge of the undertray.
Immediately noticeable was improved aerodynamic stability. The Insight is not an aerodynamically stable car at speed – it is discombobulated by, especially, the bow waves of trucks. This can be felt when slowly passing a truck heading in the same direction on a multi-lane road. As the Honda draws adjacent to the front of the truck, the very light car is pushed away from the truck. (This affect, once recognised, can be felt to a degree in lots of cars – but it’s quite clear in the Honda.) With the undertray vortex generators in place, the affect of the truck bow waves was diminished. The bow wave affect could still be felt, but it needed less steering correction.
OK, so the car was experiencing better stability, probably through reduced frontal lift. But would there be a trade-off in extra drag, resulting in increased fuel consumption? The answer to that is – no!
With the undertray vortex generators in place, the fuel consumption averaged 2.9 litres/100. In fact, on one trip the car equalled its best-ever consumption at 2.8 litres/100km – however, the traffic flow that day was particularly kind and so I don’t think that the vortex generators can be said to have helped in achieving this. But they certainly weren’t harming fuel consumption..."
I did 30 highway miles last night. On the way to Quincy, most of the trip was stop and go. Average speed was about 8 MPH until we got past the broken down car on the side of the road. (All 4 million cars that went by
had to stop and look)!
But, we drove back home in the 58 MPH range on the way back and the glue held very well.
I was trying not to get us killed by all the Saturday night drivers going
70 to 90, so I didn't take any time to notice the effects of the mods.
Didn't even think about looking at the SC2 until I got home.
Maybe old folks should just stay at home on Saturday nite!
