Where I live we can get deliveries by starships https://www.starship.xyz/. The vehicles are kind of cute when you see them in action.
Though I did wonder how they'll cope in winter-weather. I can't imagine they'd do so well on snow/ice.
Also DPD piloted something similar in Milton Keynes and is now going to do it i ten towns in the UK: https://green.dpd.co.uk/news/16
Those wheels look moderately impractical- larger wheels might have more clearance.
Reminds me that we had pneumatic tubes and miniature railways between buildings a century ago.
