Hudson Valley
Hudson Valley is a precomputed collection of 70 published roads from the 0.3.0+554b31e7 survey. This page includes 3 approved loop recipes whose named roads all resolve to published geometry.

Every other navigation app asks where you are going, then tries to get you there four minutes sooner. This one asks how much time you can spare and spends all of it on the best road within reach. The destination is the excuse.
Give it a start and a window.
This is the actual engine, answering live. It synthesises loops under your time budget, scores every segment by how much the road bends, and names each drive after the road that earns it. No sign-up, nothing saved.
One to six hours. The engine will spend all of it.
Coverage is being expanded region by region. The north-eastern US is fully surveyed — .
How twisty
Shape
Out and back to your door.
Three routes will be drawn here, coloured by how much the road actually bends.
Four things, and they are all about the drive.
A run
A time budget in, three named drives out — named for their signature road, because that is how people talk about them. The Kanawauke run. The Seven Lakes run.
Roads passport
The good roads within range, kept as a collection. The ones you have driven light up. The rest sit there.
Convoy
A group drive on one map with push-to-talk between cars. Positions are held in memory for seconds and never written down; audio never touches disk.
The recap
Every drive draws itself — the route as line art, the corners counted, the roads named, the score. Worth posting without editing.
Precomputed loops, grounded in the road survey.
Public region and loop pages are generated only for approved collections whose named roads resolve to the published canon and geometry. No runtime route generation, condition claims, or popularity rankings.
Driving is free. Membership buys the survey.
The question, the planning, the navigation, the logbook and everything you make with it are free and stay free — there is no meter on the thing the product is for. What membership will buy is the survey: the graded roads, region by region, and a number in the register. It is not for sale yet, and nothing here is a waiting list for a subscription.

It is small, and on iOS first.
Corner Research is in a private beta with a handful of drivers while road coverage expands region by region. If you want to be told when it opens up, leave an address. That is the whole ask.
There is no mailing list wired up yet, so this cannot store anything today — it will say so and hand you the address to write to instead. hello@cornerresearch.com works right now and is the same thing with fewer moving parts.
