ADAS Driver Liability & Physics Simulator

The saved physics scenario uses sixty four miles per hour, converted with one point four six six six seven to ninety three point eight seven feet per second. Multiplying by one point two reaction seconds yields one hundred twelve point six four feet. Braking distance divides squared speed by twice point seven five friction times thirty two point one seven four gravity, yielding one hundred eighty two point five seven feet. Their sum is approximately two hundred ninety five point two one feet. Both animated bars use one point five pixels per foot. This explains the page calculation, not a tested stopping distance for a real vehicle. Changing only the road friction from dry point seven five to icy point one five multiplies modeled braking distance by five. The reaction distance stays unchanged because its equation does not contain friction. Dry braking is about one hundred eighty two point five seven feet; icy braking is about nine hundred twelve point eight five feet. Both bars use point four pixels per foot and reach about seventy three and three hundred sixty five pixels. The source animation is a simplified display of these equations. Road texture, tires, grade, brake limits and sensing uncertainty are not independently validated by this simulator. The source always computes its comparison to a saved automatic braking latency of point five five eight three seconds. Subtracting that latency from one point two and multiplying by speed gives about sixty point two three feet. The actual returned value differs from an old comment mentioning fifty two point four. Toggling the assist switch changes the displayed automation level and fault labels, but does not replace the stopping physics with that latency. The bars compare one hundred twelve point six four feet of reaction travel with sixty point two three feet of displayed difference at two pixels per foot.
