We know this will be shocking given previous entries on our list, but it turns out 3-wheeled cars have historically not worked. To be fair though, the Davis Divan never really got a chance.

The Davis motor company actually raised $1.2 million for production of the vehicle through the sale of 350 dealerships, however they failed to deliver any cars to said dealers or pay their employees, ultimately leading to lawsuits from both groups. In-turn, the company’s assets were liquidated and Gary Davis was convicted of fraud and grand theft.
