VS - a swing-out door bar is a nice option to make getting in an out a lot easier. Not sure what the rules say about them if you are trying to certify the cage. Typically spring loaded or pin/clevis at the shoulder and hinged at the bottom.
Here's what I have to contend with so you get no sympathy from be. Just remove the steerig wheel, step in, and sort of fall into it, and then hope like hell no one ever has to get me out in a hurry.
