I made this version and it worked fine. Not too much math in mine. :P

#define MAX_SPEED 0.7
#define SLOW_FACTOR 0.7

forward Timer();

public OnFilterScriptInit()
{
    SetTimer("Timer",1000,1);
    return 1;
}

public Timer()
{
    new Float:x,Float:y,Float:z,veh;
    for(new i; i<MAX_PLAYERS; i++)
    {
        veh=GetPlayerVehicleID(i);
        GetVehicleVelocity(veh,x,y,z);
        if((x > MAX_SPEED || x < -MAX_SPEED) || (y > MAX_SPEED || y < -MAX_SPEED))
        {
            SetVehicleVelocity(veh,x*SLOW_FACTOR,y*SLOW_FACTOR,z);
        }
    }
}
