Yeah, I keep thinking that it's close to 90% of the safety factor, but I don't have any numbers.

Among other things, they rate safety by actual stats of numbers of people killed in accidents in different models/years cars. They measure deaths per millions of cars so a model selling ten times as many cars gets rated on an even playing field with other models.

Not the thing to read if you get all upset over turning highway deaths into statistics. But you really see which models win and lose.
In another thread, I think the gist was that head-to-head, an SUV obviously beats the smaller car, but the overall safety of the SUV was so much lower that the SUV owner was still less safe in general (rollover, losing control in emergency maneuvering, etc...).

High (very) speed coast down w/ a video cam on the dash for decent speed/time accuracy imo. Coasting to a stop can add a lot of error since the time from 30-0 is generally way more than the time from 60-30, so the difference in two profiles is harder to spot. It may be ~21s/23s compared to 6s/8s and there's a larger window for other stuff like weather to influence the results. At 90mph an average'ish car may need ~24kW for aero and 6kW for rolling. At 45mph it's only about 3kW for each, and a ~23mph it's only ~.3kW for aero and 1.5kW for rolling. The slower we go the harder it is to pick up any difference in aero. And... to complicate things, I think (this right treb?) the drag coefficient changes compared to speed, so that's just one more variable, although Iono if it's significant for car speeds. In any event, a 12% improvement in aero will result in ~27kW needed at 90mph versus the usual ~30kW, but at 45mph the difference is only~5.65kW compared to ~6kW, and at 23mph it's pretty well unpossible to figure a difference. Ideally, we could all get together and head out to the salt flats w/ a cam to do some timed decels. Newbs are limited to 140mph max speed IIRC and have to have all the safety equipment, but I'm sure 120-100mph could give us tons of great data on how certain mods influence certain cars. And, for a car like my veedub, that's gonna be limited by power, the top speed may be noticeably higher if the mods are as effective as we think they are.
