but most people who like to drive like grannies don't want seats that are "sculpted" to their bodies like a SIP carseat. that's why you see cars like buicks and cadillacs with pretty much flat seats in which you can practically slide ride across the car.
That reminds me of one of my favorite Cake songs "Stick Shifts and Safety Belts."
"Stickshifts and safetybelts,
Bucket seats have all got to go.
When we're driving in the car,
It makes my baby seem so far.
I need you here with me,
Not way over in a bucket seat.
I need you to be here with me,
Not way over in a bucket seat.
But when we're driving in my Malibu,
It's easy to get right next to you.
I say, "Baby, scoot over, please."
And then she's right there next to me."
