Okay, then just make a variable to check if he has already pressed it or not and reset it when it's released. For example:

pawn Код:

new bool:Pressed[MAX_PLAYERS] = false;

pawn Код:

forward UpdateAll();
public UpdateAll()
{
    for(new i; i < MAX_PLAYERS; i ++)
    {
        if(PlayerInfo[i][pSelection] == 1 && Pressed[i] == false)
        {
            new keys,ud,lr;
            GetPlayerKeys(i,keys,ud,lr);
            new rand = random(sizeof(RandomVeh));
            if(lr > 0)
            {
                print("Right");
                Pressed[i] = true;
            }
            else if(lr < 0)
            {
                print("Left");
                Pressed[i] = true;
            }
            else Pressed[i] = false;
        }
    }
    return 1;
}
