Easy rule of thumb: 1G = 20 mph per second.
That means that 0-60 in 2 seconds is 1.5G. Or, put another way, the Dodge Demon could accelerate straight up (if it could stick to a vertical road).
I seem to recall hearing, that some jet was the same way.
It was maybe 10 years ago, so I’m sure more can now.
Straight up.
