My dog doesn't get lost, he's a giant akita, super sweet and friendly, but I mean, he looks like a wolf. I don't want him getting out, but before he was neutered, and I added an l-footer made out of chicken-wire, he figured out ways to get out. So I would drive out to go find him and by the time I got back, he was waiting outside the door, barking to get in, usually with some stolen toy at his feet. Now, I've doggy-proofed the yard so he can't get out, but I don't know how he does it but he never gets lost. No matter how far he goes, he's always back before dinner time. So that's why I'm always thinking that self-driving cars are not going to happen anytime soon. Everyone's underestimated the problem.
