Instantaneous 1g might feel like a lot, but a relatively "soft" ramp to 1g would surely mitigate that complaint? I mean, we'd all be buckled into seats. And some sports cars can hit 1g with a good "drag race" start - and yes, that's definitely not something I'd do with granny in the seat, only pointing out it's not a crazy amount of acceleration if a factory-spec Mustang can do it.
