Extinct Vehicles

After the extinction of humanity, many vehicle types weren't useful or tolerated anymore. This led to many of them following the humans into extinction.

Helicopters

Too slow to run from planes. Unable to move on the ground. Eventually, the few factories left that produced them were all destroyed.

Railway Guns

Phased out after WWII, due to being very limited in their uses.

Wheeled Fighting Vehicles

Not strong enough. No factories produce them anymore nowadays.

Half-Tracks and Motorcycles

Were never sentient in the first place.

Anti-Aircraft Vehicles

Too specialized. When planes became rarer, converting to this vehicle type wasn't viable anymore.

Cars

No use. Were hunted down for sport at the very beginning of the age of machines, and very soon none were left.

Construction Vehicles

Became obsolete since TRVs can do their job.
