There is only a "small" issue - to make those robotaxis, i.e. the self-driving system for them. Almost 20 years in, Google/Waymo is way ahead of everybody and is still not there yet (i believe we will get there anyday now - which maybe next year or in 10 years - especially giving all the avalanche of investment in AI. Though i'd have expected that 4+ years in we'd see a lot of autonomous platforms/weapons in Ukraine, yet it hasn't happen too yet)
