Low Roof line on the Gen 5 Prius

5-11. I've never hit my head or had to contort to get out.
Weird.

I have absolutely no issues with any control placement or anything with the car.
Perfect car for me.
YMMV obviously

 

Some of this will be age and flexibility related. I'm 6'2", and have folded myself into lots of awkward little cars when I was younger. How I get into and out of a Prius now takes into account some knee and back injuries.

A manufacturer is only going to do so much for the thin ends of the bell curve. I believe there is a range of cheap shoe manufacturers that don't even make size 13 shoes. I've never seen a size 13 shoe at Costco. Some lines of trousers don't come in a 34 inch waist and 34 inch inseam. These companies aren't losing much just because I don't buy from them.

The same rationale should work for cars. If you are professional basketball tall, you weren't going to look for a Prius anyway.

 

I'm about the same size as you and in my 50's. The lower roof line takes a bit of getting used to. It is definitely more difficult to enter. I don't recommend this vehicle to people with mobility issues. However, it is a VERY fun car to drive. I drives better than the 6 cylinder convertible Mustang that we used to own.
