@320:
Actually I use the fogs for driving quite a bit. Not so much for fog, but for road hazards. Pennsylvania is infamously know for have terrible roads. We have pot holes that will bend a wheel if you hit them. Its absolutely terrible in this state, and even worse the road crews "fix" something by doing half ass repairs. They install storm drains without properly settling the ground. So we have water run offs that drop off the side of the road ~6"-8". The fogs help catch these tire eating holes, especially at night in unfamiliar areas.

So for the news, took some videos while I was out doing my coast tests. After reviewing the videos, timing the changes, doing some map checking, and rough estimations, here are my results!
Baseline for the Coast Tests:
Average 60-50 Time: 8.11 Seconds (out of 9 runs)
Average 50-40 Time: 9.07 Seconds (out of 8 runs, one run hit an uphill and vastly skewed time)
Front Bumper Block (without wheel/suspension blocks installed)
Average 60-50 Time: 8.76 Seconds (out of 10 runs)
Average 50-40 Time: 9.63 Seconds (out of 9 runs, lost 50-40 because someone pulled out in front while I was coasting.)
The accuracy of these times should be around +/- 0.25 seconds. I tried to make all the runs in the same locations along the roads, weather was fairly consistent Saturday as well. I took multiple timings of the videos and then used those to get a average time for each test.
Other Details:
Baseline Test:
70*F, mid morning (9 am) 8/14/2010
Rural Highway, start to end ~125ft change in elevation (net result its uphill the whole way)
Tire pressure - not recorded
~1/2 Tank of gas
Front Bumper Block Test
74*F, Mid day (noon) 8/14/2010
Rural Highway, start to end ~125ft change in elevation (net result its uphill the whole way)
Tire pressure - not recorded, but unchanged
~1/2 Tank of gas (about 1 gallon less, but I had a bag of tools on this run)

The interesting bit was I never knew the road I travel frequently was moderately uphill/downhill depending on direction of travel. Found this out in an interesting sort of way!
Without the bumper block, I took more video. I actually filled my SD card on my camera, so I had no return runs with the bumper block installed. So the trip out was 8.11 seconds/9.07 seconds without bumper block. The return trip was 10.04 seconds/10.72 seconds without bumper block. I was actually pretty confused by this result at first. Trying to find a solution I checked into the topography of the area and found out where my route started at ~525 feet above sea level. The end of the trip is ~650ft above sea level. So in the end I could only compare data for the outward trips.
The real test will be coming up this week for work. I'm at ~300 miles on my current tank and will fill up on my way home from work Monday.
