The guy in question paid $450 for 3 months health insurance, or $150 a month (less than the $197.15 you suggested).
WRT the $70/mo, the supplies listed are inadequate for a months supply for a type 1 diabetic.
Buying diabetes supplies is expensive. They may not cost much to produce, but 50 test strips costs about £25 in the UK over-the-counter (or $1 per strip). At 5 tests a day, thats $150/month just for test strips. I've not had to buy any other diabetes supplies myself, so I am unsure of just how much they cost.
You seem very sure in the appropriateness of speed limits everywhere. It is also rather naive and judgmental to refer to anyone driving over the limit as an idiot.
The limit may not be appropriate, but I would be very surprised if more than about 10% of drivers could accurately assess the appropriate maximum and minimum speeds for any stretch of road, and the vast majority of drivers would reckon that they would be within those 10%.
I wouldn't trust most people to set their own limits, as they don't have a clue what their (or their vehicles) capabilities are.
There should also be a display as to what the cruise control is set to.
Surely thats the same speedo you use to tell what speed you are doing when cruise control isn't enabled?
