On my own include, I use this method:

PHP код:

stock Float:getPlayerSpeed(playerid)
{
    new Float:x, Float:y, Float:z;
    if(IsPlayerInAnyVehicle(playerid))
    {
        GetVehicleVelocity(GetPlayerVehicleID(playerid), x, y, z);
        return (floatsqroot(x * x + y * y + z * z) * 180.00);
    }
    
    return 0.0;
} 


and works.
