Self-driving cars, selfie sticks, drones, touchscreen devices, e-cigarettes, jetpacks, and many other things seem like fairly modern inventions. Indeed, most of their "inventors" list them as newly invented and even go as far as seeking patents. But the fact is, many of these "inventions" have already been in existence for quite some time. They may have earlier lookalikes that ended up not going into production or that went into limited production due to one reason or another. Some also made it into full production but were recalled due to poor sales.
