15: Honda Insight (First Generation)
The dawn of the new millennium was a strange time for automakers and technology. The dot-com boom was among us, and hybrids were a new type of car. Honda released the quirky Insight to much avail in 2000. The car had a two-seater design and looked like it came out of the future. The problem is that the original Insight was not that practical of a car at all (via Motor Biscuit).

Honda couldn’t justify the design of the car to the average Civic buyer who needed a backseat. The performance of the Insight was lethargic at best, which turned many consumers off. The original Insight could have been much more, but Honda wasn’t innovative. Its design was too limited and the price tag was a tad bit too high.
