I think he means that the headers come from the device making the call, not the one receing it, so a pedo should be able to change the headers of my device which is not that easy.
Then yes, the receing end could simply ignore the header anyway, it would be way easier.
That’s a problem, I agree, but you don’t design a new car model around edge cases.
True.
Again, it depend on the target market. In EU it was relatively common to have 2 cars: a small one for the day by day commute (where other options are not available) and other tasks like taking the kids to/from school, small trip to the grocery store and so on, and a bigger one for the long travel.
It is still true outside the big cities, where services maybe are not that near and normally there are very few options for public transportation. And I don’t think that having a small car for the day by day and rent a bigger one for longer trip is really that bad.
Also, consider that often a really big car it not an option in places where street are really narrow to the point you are forced to buy small car (common outside most of the big cities)
I think you are out of price range. I don’t know is US (given the use of dollars), but in EU a 120K car is not a common car, I mean, the big cars like the Renault Espace are in the range of 50/70 k, a 120K car is an entry level luxury car here.
