Sorry for having been cryptic  about 'many things' - I meant to say that I hope that MikroTik querying the DHCPv6-PD server in the starlink infrastructure might work ok from  a car as well.  This would be one big advantage of using starlink instead of a 4G-5G link in a car (the 4G-5G cellular networks only give /64s to end users, and the android smartphones dont run DHCPv6-PD Clients).
