Bench seats or bucket seats
And now for something completely different ....
In my opinion the greatest leap BACKWARDS in automobile development was replacing the bench front seat with bucket seats.
The first car I bought brand new (in 1963) was a Ford Cortina 1500. It could fit 6 adults with passable comfort, had a boot with almost the same capacity as a family car, not to mention doing 32 MPG in town and 38 MPG in the country.
Regardless of the size of the car, by replacing the front bench seat with bucket seats, the carrying capacity is immediately reduced from 6 to 5.
I was looking at a recent model Jeep Cherokee today. Even the rear seat was designed to seat only two people.
Additionally I have never sat in ANY bucket seat that gave the support to the lower back in the way every bench seat did.
And as for extra-curricular activities -- well you just can't do squat in any newly designed car.
