Title says all,

is it possible, if so, how?

As far as I know it's only possible to prevent a vehicle from gaining speed.
At this time I do not believe it's possible to prevent a vehicle from reducing it's speed.
There are ways to make a vehicle maintain it's speed, but it can be over run by pressing the brake.

Use SetVehicleVelocity and detect when they hit their braking key (whether it be their Spacebar or S by default).

Not sure if that would work, but if it does you will have some sort of "not smooth driving". Car stopping for a sec, then accelerating. That will look awkward

It'll work to serve it's purpose (it will look awkward though).

I was hoping to detect when they press 'S' or the decelerate key.

The only solution is the one listed above, though it'll be very glitched and look bad which is why I didn't suggest doing it.

I was hoping something like, if they press 's' nothing happens? or their decelerate key.

Turn the engine off using SetVehicleParamsEx (https://sampwiki.blast.hk/wiki/SetVehicleParamsEx). That will of course prevent accelaration as well.

Nope, there is no way to bypass it.
I do have an idea though, I will test it out then post the code here if it works.

This will make it decelerate as-well, as the engine is off.
