The Highway Code tables are based on an average family car in the 1960s (IIRC) when the tables were first introduced. They're ridiculously long distances for modern cars, though AIUI the "thinking time" part is nowadays thought to be too low.
- grkvlt 8y agoStill, that's not a bad thing, per se. If we underestimate based on a vaguely remembered overestimated value from the highway code based on 1960s cars, then the effects cancel out and we're basically correct for modern vehicles?
- gsnedders 8y agoI /think/ I recall seeing something that claimed with longer reaction times it actually ended up worse overall. That said, I think often the bigger problem is people not realising especially in more unusual conditions (like snow in much of Britain) quite how much longer braking distances become.
