In the case of self-driving cars, I'm pretty sure the DMV has already identified the edge cases that need to be watched out for and any incidents after the first one can presumably be resolved very quickly.
Innovation in tech transport is necessarily going to involve a certain amount of risk to life and limb. Even today there's car and plane accidents but we accept that as the price we pay for convenience. FTL is probably going to kill a lot of people before it becomes worth the risk. Although in this case, the tech will probably end up saving a lot more people than it ends up killing, possibly even in its current state. The only thing to really watch out for is a sense of complacency where the human doesn't take over when required. To prevent that, what we really need is a point-to-point parking solution where you just input your destination, go to sleep, and wake up at your destination like that mystical Welsh artifact. In order to facilitate this, what we really need is the ability for a car to maneuver in a parking lot. It might require some extra hardware around the parking area, but I think it should be possible even today. Witness Oculus Rift. If people are willing to spring for a garage door opener, why not a feature that allows the car to park itself and power down with optional alarm?
From there we should expand to the ability to navigate a parking lot in a general case. When my dad first taught me to drive, he didn't take me on the freeway. He took me to a parking lot.
What's really needed is for people to become comfortable with self-driving cars on a consumer level so we're not innundated with endless speculations that defeat the purpose of the undertaking in the first place. For example, right now Dubai is offering an air taxi service and Lilium built a scale protoype in a cofounder's living room in a week. Meanwhile. Moller's been building these things since the 60s but last I checked, wouldn't untether his Skycar because of insurance.
either overpriced, uninteresting. or hard to find in the app store
Nice set of rationalizations. Hard to find in the app store isn't something a dev can do shit about is it? Really, the only reason any app is hard to find is if Apple has shitty programmers who can't even get their back-end infrastructure right.
