And those are completely believable or did already exist.
1G (analog cellular networks) already existed. NASA administrator might have had Motorola DynaTAC 8000X in 1983 even in our timeline.
EV car that runs 60 miles with a single charge is a real change to our timeline, but believable if the investment into EV would have been huge (needed in the moon and space in large quantities).
Overall, the worldbuilding that went into that show is impressive. Many events in the show actually happened, but are resolved differently or have different consequences.
And yet somehow the whole S2 in centered about Space Shuttle program - years after a successful Sea Dragon launch. This was the most unbelievable development in the whole show.
In the second season they show new spacecraft designs that are based on actual proposals. Like the Sea Dragon super heavy-lift launch vehicle.
They also introduce androgynous mating system that is very similar to International Docking System Standard (IDSS) https://www.internationaldockingstandard.com/
