Would some of you like to go back to 1966 cars, I certain would not a it was far to dangerous.
Yes and no. There has been much progress. Electronic ignition and fuel injection have improved reliability. Disc brakes have improved stopping ability. A better understanding of body construction means modern cars crash better and rust less. Better lubricants and sealed for life joints have reduced servicing requirements. Better suspension and tyre design has improved road holding (but it seems most of today's cars are set up with stiffer sports type suspension - I'm sure at least some people would like the soft riding option).
But personally, I could quite happily do without all the electronic gadgets and screens that modern cars have. I see them as an unnecessary distraction from the driving experience.
