You're imagining inventing a car and feeling the wind in your hair on the open road, others are imagining being stuck in traffic and cities becoming more and more dominated by parking lots. You're criticizing them for a lack of vision, but that's not correct; they're peering into the same future, and seeing something different.
That doesn't make them "antiprogress," they're critics with concerns that would be worth engaging with instead of dismissing. If you care about this project and you want to make the best version of it - ask them why they think that way instead of responding to the version of their concerns which is in your head, and then give some thought to how you could address it.
(I'm ambivalent leaning towards skeptical, so not much much of a dog in the race, trying to bridge a miscommunication.)
