Details like that certainly need to be worked out but such criticisms are usually made in a way that ignores the bigger picture.

Internal combustion engines contribute substantially to pollution and human-caused climate change. Motor vehicle accidents maim and kill lots of people every year yet fans of that form of transportation hand wave it off as irrelevant.

We don't have to speed blindly into the future on our current vector. We can change course. It will take work and creative solutions.

Not to say such concerns shouldn't be brought up but they shouldn't be brought up in a manner that sounds entirely dismissive of a new solution with a lot of promise. Ideally, it gets brought up in a more constructive fashion overall that is more conducive to meaningful engagement and less prone to simply making people mad or defensive.
