I just saw a show on the Motor Trend channel called "Seduced by Speed - Car to Die For" (S1: E1).
It was about a 3 wheeled car from 1975 that promised to revolutionize the car industry.
It turned out to be a massive fraud.
HBO is also doing a 4 part series called "The Lady and the Dale". The first 3 episodes re-air today at 5:00 central.
The motor trend show is worth a watch. Available on comcast On demand.
Even Jay Leno tweeted about it! I wonder how I missed this story before?
Only the second episode of the HBO series discussed the Dale. The rest of it focused on Liz Carmichael and her transgender story. Ioswa's link above covers most of the actual car detail.
I watched the entire series on HBO. It is more a transgender story about Carmichael. An interesting twist was that Tucker Carlson's father Richard was the reporter in California that led the effort to bring down the Dale company.
