Así es. Aquí la explicación de Ohad, que es CONFIDENCIAL:
The calculation is based on weight, which is how many people have ever driven on a segment.
Divide all the segments in the country to half percentiles, removing segments with a weight value of more than 400,000. (so now we have 200 equally sized groups of segments sorted by weights).
The first 97.5% of the segments in the country - are available for everyone
98% - 2 cones and up
98.5% - 3 cones and up
99% - 4 cones and up
99.5%+ - 5 cones and up
