People are some of the worst drivers around, they cause all kinds of problems with cluelessness and inattention and they crash and die and kill and injure in all sorts of stupid ways. They get drunk, high, check their phone, fall asleep, speed, show off
I think it's great that there are still companies out there throwing research into moonshot types of research projects like this. Automobile deaths are perhaps the biggest and most persistent pandemic we've faced, we've been facing for a hundred years, and it kills and maims young and old alike. Millions of people dead over the years.
Many were willing to relax some of the protocols around vaccine testing to bring the covid vaccines in to use earlier, put mandates and coercion around them, and yes some suffered adverse reactions and even died from them. Still, it was thought to be a reasonable compromise by many.
I hope we don't go the other way on other technology that can advance society and potentially save lives just because not everything goes perfectly from the start, or we get stuck in the pharmaceutical corporations = bad mindset.
Not to say there perhaps shouldn't be more regulation around it, but a serious and careful study of risks and benefits I think is appropriate rather than handwringing and outrage.
