They would just not remember driving their car or landing the plane, they still do the action in the 'deleted' time. It's more that sense of walking down the road and realizing that you can't remember a part of your walk.
but if time catches up at the moment when you're in the middle of merging or something, and you don't even remember starting to merge, who's to say you wouldn't either jerk the wheel straight due to being disoriented, or over-correct and slam into the adjacent lane because you don't remember having merged.
Who's to say a pilot might not disengage the landing gear because they don't remember having engaged it? (assuming the control for those two actions is the same button, and not a switch.) maybe more realistically, what's the percentage chance that a million people immediately take an unsafe dose of medication because they don't remember having already taken it in that 5 second period that no longer exists?
It's not as if people don't notice the compression of time, abbaccio was visibly confused and hesitated at finishing the sentence he was trying to say when he appeared to have teleported.
it's possible the potential implications are just never addressed, and it is something most people just never notice. but the way it was portrayed from the gang's perspective just makes my brain break.
I'm not a "oh no plothole" type of guy, i honestly don't care if these details aren't important, it's just that the way that this show has trained me to think about powers and special abilities inevitably sends me down this rabbit hole. because like, who knows, it might actually end up being important to the story?
