Edited sentence: Another alternative to vehicular cycling, "segregated cycling", is available in areas with sufficient segregated cycle facilities to support cycling as transportation without sharing roads with vehicular traffic.Even in countries with relatively large investments in segregated cycling facilities, most trips using such facilities are relatively short.Never-the-less, even in such areas cyclists are legally required to operate vehicularly when riding on roads, and benefit in terms of safety when they do.Practically speaking, segregated cycling is limited in utility compared to vehicular cycling since the infrastructure for vehicular cycling, roadways, is essentially ubiquitous, and the infrastructure for segregated cycling is very limited.Such environments have evolved in some cities and countries, usually coupled with factors that make motoring relatively inconvenient, inefficient or overly expensive.Transitioning between segregated cycling on segregated facilities and vehicular cycling on roadways requires similar caution as that required when transitioning between pedestrian and vehicular cycling
