What do those cars have in common?


They're all either fifty years old or replicas of fifty year old cars.

Old cars which are needlessly heavy for the amount of body rigidity they have and woefully unsafe compared to modern sportscars.

I hope you get what I mean
How wide is your car going to be? Even with a full spaceframe, you cannot prevent damage to the main chassis during a side impact.

Most cars nowadays already have front subframes that can be replaced after an accident, but it is impossible to prevent damage to the safety cell.

To build a car the way you want it would result in a car that is at least three feet wider than a regular car, and several feet longer. And much heavier, because instead of having a unitary body, it will have a metal skin, a spaceframe and a ladder.

Nobody wants a two ton Civic.
