I would claim that I did whatever Lightning McQueen did to end up in Radiator Springs, but I don't remember the details!

I measure distances on Google Maps by selecting start points and end points.

In the video they say that the coastdown test was done at a 3.1% (IIRC) INCLINE. (uphill)
It stopped sooner than 2 miles, then calculations put the distance at 2 miles.

ie: There was NO coasting down a mountain with 3 added tons of ballast here.

Six miles at 6%.
I’ve gone down that pass in active snow storms multiple times at full speed with snow tires. Constantly passing slow cars who are in the right lane

As the conversation has gone on to:
How far can you coast down a mountain pass?
The implication is that Aptera is telling the world horrible lies and that their test vehicle came to a screeching halt in no more than 3 feet!???
WhatTF's that all about!?

Personally I think a 'In both directions' coast down test is a good indicator of improvements in aero + rolling resistance efficiency (at a constant weight) and it's a wonder there is not a whole lot more of it going on around here!?

As aero drops off to insignificant at around... what? 25 mph; shouldn't 75 to 25 mph coast down distance be a useful metric on Ecomodder?
