Well I'm Pretty sure if a human were driving my roomba(which is freaking awesome btw) it wouldn't keep locking itself in the bathroom... When we get home everyday (or at least quite often) we get to play the where is my roomba game.

Yeah, but I also imagine that the margin of error for a Roomba running around in an apartment is a lot bigger than for a driverless car on a public road or a pilotless drone dropping off a package. That's probably why a driverless Prius costs an extra $150K but a driverless Roomba doesn't.
