🤯 A visual physics lesson at 80 km/h.
Enthusiasts launched a man from a moving truck in the opposite direction - at the same speed the car was traveling.
The experiment spectacularly showed how relative speed works.

Which way he’s facing makes no difference. Relative to the ground, by which we are measuring his speed and on which he comes to rest, he is decelerating. Just as a seat belt presses against your waste and chest to decelerate you when braking hard, the chair he’s sitting in is doing the same, but against his entire back.
I will however agree relative to the moving vehicle he is accelerating in the opposite direction of motion, but that not the frame of reference by which we’ve documented his moving velocity.

The question is what it would FEEL like, not the technical physics.
Exactly.
Otherwise he might not have been accelerating at all compared to a meteor on the other side of the galaxy (by pure chance).
Acceleration is a vector with magnitude and direction.
