* Lidar startups vie for supremacy: https://tmsnrt.rs/2EAsKuC. : OXFORD, England (Reuters) - Far from the sunny, wide streets of Phoenix, where Waymo’s self-driving taxis ply their trade, a handful of European startups are developing driverless cars to navigate the clogged, chaotic, rain-swept roads of European cities. Startups such as Oxbotica, FiveAI and Wayve that are testing cars in Britain say the old continent is a unique proposition with quirks and challenges that tech giant Alphabet’s (GOOGL.O) Waymo, Uber (UBER.N), Aurora and others have yet to crack.
