NASA’s code runs on devices that have am very specific missions. They can test all of the edge cases because they’re going from A to B once and they have a decade to prepare that journey. People riding electric scooters and etc will run into more variability each day than NASA will in a whole mission.

I crashed and broke my back on a two wheeled scooter in SF due to a pedestrian walking on a red don’t walk sign, for example.

Plus, none of these companies are doing NASA quality assurance or anything close, so why even compare them to NASA?
