If the road rules prevent us using a mobile phone, based on the distraction it presents to to the driver, then some may question if your condition presents a similar distraction.
If so, and I say this with all due respect, should someone be at the reins of a 2 tonne SUV if not fully committed to their responsibilities?
I say this as a father with kids walking on the street and soon to drive, and as a husband of someone with chronic pain and the respective treatment
Hope you find a solution and I'm sorry to hear about your condition.
