As far as I know, there's nothing stopping car companies from having the torque converter lockup at low speeds, other than a slight added cost in having a stronger lockup clutch. In fact, I hope there is a good reason they don't do this, as otherwise they have been wasting huge amounts of gas for the sake of a little bit of extra profit.
It might be interesting to note that early Chrysler products here in the states before most companies started adding an overdrive to their autos advertised lockup torque converters to save gas. If they aren't using them now I would like to know why. It is possible to buy lockup torque converters for performance applications here as well.
