@starshineIn my opinion: The only time self-driving vehicles should exist is either a) at a museum of technological history, b) in isolated cases where low-speed ground transport is needed, like on enclosed sites, like quarries, transferring people around exhibition centres/airports, etc, or as search/rescue vehicles.
I feel the latter is a great use-case for autonomous vehicles because the operation of quarry vehicles is a tedious, monotonous role that requires vehicles to climb up and down. There's no other obstacles in the way. Ground rescue vehicles require you to send someone out there who may not come back - so removing that person removes that risk entirely, especially in a dangerous situation.
