I have driven and been in several and had never noticed any interference or inconvenience, however when we initially tacked mine together to confirm clearance of the doors, window cranks, hardtop bolts etc. I became a little concerned, especially since this is a 78’ and later 40’s have slightly wider doors.
After trail riding all weekend, getting in and out what seemed like 100 times, I never adjusted my driving position or felt it changed the way I got in or out or operated the clutch. Visually tight yes, but not functionally in any way I noticed.

My experience is similar. Welded up the MetalTech cage with the A pillars as close as possible to the doors, but so they still close. The bottom of the A pillar is close to the clutch pedal; you quickly get used to feeling the A pillar with the outside edge of your foot when you engage the clutch pedal.
