> It's really ashame that we'll never see versions of those mechanical cars combined with the manufacturing precision and quality control available today.
The car that makes me cry a little every time on the what-could-have-been topic is the Honda CRX HF. 54 MPG in 1988. Most cars can't match that today over 30 years later.
If Honda was allowed to do a modern version with some use of carbon fiber for even more lightness and all the advances in fuel injection tuning and engine manufacturing, surely we could have a ~70+ MPG CRX by now.
Sure there are one-offs and some drop-ins available, but they'll never get dialed in the way cars do after a year or two of mass production.
