Now, say I am a young teenager looking to borrow my parents Focus. They have given me a programmed MyKey with speed limits, etc. If I decide to start the car with a remote start fob, it will shut down when I open the door so that I have to use the MyKey to start the vehicle.....and I am forced to drive with limited use. Now, if the remote start was programmed so that it stayed running in a seamless operation as we are often used to with older remote starts, I have the ability to start the vehicle with a remote start and even though I have the MyKey in my pocket, the car is still running off of the non-limited key ID that was the remote start fob. The young teenager can bypass the MyKey system completely!

That is why the vehicle shuts down when you open the door. It used to be bank 2/option 7 for the one button remote starts to shut down this feature but I'm not sure how to do it with the new ones. I'll keep you guys posted when I get a chance to play around with one as I usually turn this feature off for most people as I have found that 95% of the people will never use MyKey.
Hmmmm...

How is this any different for proximity fobs that remember what positions individual drivers want the seats, steering wheel, mirrors, and climate settings to be?

For example, in my '09 CTS-V with proximity fobs my girlfriend and I had different driver's settings and regardless of who started the car with their remote start, the car would recognize the particular person getting into the car (based on which fob they carried) and then adjust the seats, mirrors etc. appropriately when the person got into the car - all without requiring a re-start. Come to think of it, my Infiniti M45 was the same way.

I can't see how this would be any different for a car that remembered certain parameters (like speed, stereo volume, etc.) in a parental-control situation. Teenager starts car with remote start, car starts with absolutely no clue as to what restrictions to place on operation, but when a fob gets close enough the car can recognize that fob as having certain restrictions and then enables those restrictions, all without having to re-start the car.

I'm not saying that what you described is not indeed how the car was designed, I'm just saying that I can't understand WHY is was designed that way.

If I had designed the car (which I obviously didn't, nor do I know how to design a car) I would have made it so that when you remotely started the car it would start in a "blank slate" mode so that it is now running without any sort of preference as to restrictions, preferences, etc. However, when someone gets into the car the engine will remain running and will continue to run (What's the point of having a remote start if you need to start the car again when you get inside?) but when you put your foot down on the brake to place the car in gear, the car's brain now senses the presence of the fob as a condition of starting (and thus the reason the car would shut off if you put your foot on the brake without the presence of a fob, thus preventing someone from breaking a window and stealing your car on a cold morning) and would then realize, "Hey...there's a fob present that's telling me to limit speed and stereo volume, etc." At least that's the way I would design it.
