The way I sit while driving is very different from typing

Typing I'm not able to recline and comfortably type. It's possibly a different chair, desk, keyboard, and monitor setup could help with this but I'm self-employed right now and not able to shell that out for what would amount to experiments which I don't expect to be particularly fruitful.

I have worked in a number of offices and with a variety of setups when employers were footing the bill, and have yet to find one that was significantly more comfortable than my current setup.

When driving I'm in much more of a relaxed reclining position and just steering. Long distances I can add cruise control to the mix. Making minor adjustments to the steering wheel is completely different from the wrist/fingertip stress of typing, and good posture when working at a desk requires being more upright, which in my experience ends up putting more stress on my back and neck also.
