5: Clutchless Manual
In the ’80s, pretty much every standard model car came with a manual transmission. An automatic was considered a luxury item around this time. But for a lot of consumers, the task of driving a manual transmission was a pain. This is why a few automakers got together and tried to develop a clutchless manual transmission. The problem was that these transmissions were expensive to repair and time-consuming.

Clutchless manuals faded into obscurity pretty quickly. However, in recent years there have been a few enthusiast cars that are being designed to use a clutchless manual. Hyundai is at the forefront of this trying to bring that obscure technology back into the mainstream. Time will tell if the clutchless manual can see the light of day again.
