* Inventory: Car dealerships often have large inventories of new and used cars on their lots. These cars are *for sale*, not necessarily *undriven*. Seeing many cars on a lot doesn't mean they're not driven—dealerships use them for test drives and sometimes move them around.
* Rental fleets: Rental car companies buy many vehicles, and while these are driven, they are not privately owned in the same way as a personal vehicle. This large pool of vehicles might contribute to the feeling that there are many "unused" cars.
* Used car market: The used car market is vast. Many used cars are bought and sold, and some might sit unsold for periods of time on dealer lots or online marketplaces. This doesn't mean they're inherently *never* driven; they might be awaiting the right buyer or undergo some maintenance before resale.
* Vehicle storage: People may own vehicles they don't regularly drive, perhaps because they have multiple vehicles, one is a classic or collector car, or it's kept for seasonal use. This doesn't mean they are "not driven," simply infrequently driven.
* Statistical misinterpretations: The source of your claim about "half of the cars sold" is crucial. Without a reliable source and specific definition of "not driven," the statement is likely an exaggeration or misunderstanding.
In short, while there are undoubtedly many cars that are driven infrequently or sit unused for extended periods, the claim that half of all sold cars fall into this category is highly questionable and lacks supporting evidence.
