The road in first place is over here near me. The problem with driving in scenic roads is you can either drive or check the scenery. |

Number 21 is close to me. There are places along the route where you can stop and enjoy the scenery. I have also gone up this road a couple of times on bicycle, where you have more time to see the view. |

Looks a bit steep to ride the bike! I prefer to ride in leveled roads. They are running a competition and the prize is flight ot Portugal, a weeks holiday and a Mercedes Benz to drive. I already have all that, thank you! Am I a privileged person, or what?! The theory behind the criteria of selection is interesting though: http://www.avisbestroad.com/downloads/V8%20ADR%20-%20the%20workings.pdf Sometimes I need good examples to explain why my kids should study their math, beyond "because I said so".

I like that kind of math/physics, but I disagree on many of the assumptions. A formula one will perhaps do 5G at high speed, but not at low speed. It lacks downforce.
They also assume constant acceleration, while most cars accelerate a lot better at low speeds than high speeds. When I am driving on a twisty road, I don't finish the braking before the corners, and start accelerating after the road is straight again. I brake deep into the corners, and accelerate through the rest of the corner. When I drive alone, I prefer an ADR ratio of zero! :-) |

Ove, your driving skill and personal preference are rather atypical. The math behind the this takes several "short cuts" as you noticed. For my personal taste in driving, I like the road to have all turns built to a radius that allow me to cruise and steer around most of them without need to do much braking and accelerating. I do so in my daily commute, and end up turning a bit fast in the mercedes ex-taxi, eating up tires real fast, but it cant accelerate quickly out of the curves. I believe the assumption of constant acceleration to keep formulae simple, is totally off reality. Plus, when driving in a road i don't know, I must keep a safe margin "for error", as i can only see the turns as they unfold in front of me, I can't tell a 60º from a 90º until i am deep into the turn, so I brake early and then accelerate out of the corner, most times exit the turn at full acceleration. I believe this is much different from a constant lateral acceleration. I value much a long straight from time to time, to stretch 3rd gear, otherwise is just cruising after the slowest moving vehicle ahead. The article was still a valuable effort to a systematic approach, |
