Perceiving Extremely Fast Vehicles

[MintyBoi1]

So let’s say a character is inside a vehicle like a train constantly moving faster than a normal person can respond. As fast as a bullet for example. And the character can fight like normal while the vehicle is moving. Would the character’s combat/reactions scale to the vehicle’s speed since they aren’t at all disoriented by moving so fast?

No, there's something called... I believe relative velocity or some shit like Newtons laws, correct me if I'm wrong but anyways, the main thing is that if you move in a train going bullet speed, your body's speed is 300m/s, if you were to punch it would be going 314 m/s. However, the 300 m/s is stable to the vehicle, not you, so in reality you'd be punching at 14 m/s. Kinda getting it? Or should I explain more.

I think I get it, thanks

Na.

They are only moving from the perspective of people outside the train who aren't moving. From their own perspective, however, they are at rest.

For example, when you sit on a bus to go somewhere, its not your own body that's moving, from your own perspective of course, and you instead feel like the outside world is moving backwards and you stay still on your seat. The opposite happens for the outside world, where they are standing at a point and perceive you (or the bus to be exact) as moving. That of course doesn't mean you scale to the bus's speed physically, however.

Assuming they are inside a train or bus, that automatically means they are inside some covered area, so there's also no air resistance against their bodies (or even if there is, it's not significant enough) so there's nothing to calculate based off of that either.

HOWEVER, cases where vehicular speed is indeed considered is where the character has some supernatural ability to spawn a vehicle (or anything they can ride on) or turn into one himself, to travel or to fight (like in space movies, characters may use robotic armors/mechas to fight and travel), which technically counts as their speed, be that flight speed, travel speed or fighting speed.
