Actually it is pretty easy to get in and out of for me anyway. The top of the door is only 30 inches off the ground.
I agree that a great handling car can avoid a lot of crashes at higher speeds, but then there is always the time no matter how good of a defensive, courteous, or skilled driver you can be, you get stuck in a spot you can't drive out of. Like me, in my only accident 26 years ago sitting in the left turn lane of a 6 lane road, when some great driver was spinning out of control in his Mustang in a light rain at night. Saw it coming, but when his car shot over to my side of the road, and the moment I saw he was coming my way going about 40mph, in less than 1 second, all I could do was nothing...BAM. Folded the front of the car to the front tires, and snapped my wrist. It was an 85 Toyota MR2, but it really soaked up the impact with only a trunk in the front, No air bags, ABS, etc. If I had been in a 55 Chevy, either I wouldn't be typing this, or I would be asking "Where's my Baseball?"
