That was my thought too. Wonder what the timeframe was because if it’s data collected over multiple years you’d expect to see an overrepresentation of vehicles that were sold through that whole period while models that get discontinued, or launched in that timeframe would be underreported. Also maybe some demographics, like was the high number of S-10 while it was available new and presumably driven by people that recently purchased those new vehicles, or is it 10+ years after it stopped being sold when it’s the old farm shitbox or a young guys first truck.
Some systems already have that. Replaced a switch yesterday and re-arranged some things on my network board and got a HomeKit notification that some things were offline and when it came back. Knowing when something goes offline isn’t as useful as keeping things up though. With something like a hardwired camera/NVR, even if your ISP service is interrupted the cameras can still record, and you can put a UPS there to keep things going, even if the rest of the network is down.
