Yup. And when's the last time you saw someone rebuilding a 2010 vehicle? Plenty of those still on the market...yet here we have a situation where a woman and her son are restoring a vehicle that is only five years old.
That doesn't strike you as odd?
No, and that's the point of Fallout. Remember, that same Fallout 1 intro was hawking a Corvega with "no electronics, no computers" for 199,999.99 - meaning it was a economy car. A Giddyup Buttercup children's toy cost 16,999.99. A beer at a restaurant attached to a brewery in Boston ran you anywhere from $55 to $75 per bottle.
The US is still depicted as a consumer culture, but that culture is choking to death on itself...because of the shortages.
Two, by my recollection. The damaged Enclave Mister Handy outside of Klamath, and Toto the Robobrain in Shady Sands. Both from Fallout 2 - but then, Fallout 1 was a pretty short game, all things considered and I get the impression between the Followers, Gun Runners, Brotherhood, and Master all bits of advanced tech were quickly gobbled up in the Core Region. The Boneyard certainly lives up to its name, at any rate.
Terminals in Fallout 3/New Vegas explain this. Corporate America was investing more in robots to replace the Human workforce (which wasn't doing anything for inflation and the shortages crisis).
The only Vault I know of that had a robot was 101, and Andy was an aberration, considering in other Vaults bringing robots (even pets) was disallowed. Likely because they'd interfere with experiment parameters.
Surly robot butlers, mind you. "How May I Serve You Master? ....not that i really want to." I'll admit he makes little sense in Megaton, but in Tenpenny Tower he's thematically appropriate.
And not much else.
Fallout 4 pulled back on that, and I do agree it was odd just encountering the random Robobrain/Protectron/Sentry Bot wandering the wastes in Fallout 3.
