Intentional design decision? Why on earth would that decision be made?!?!?
List of things that update DST on their own:
1. My three computers
2. My tablet
3. My phone
4. My alarm clock
5. My kitchen appliances
6. My TVs and other entertainment devices
7. My thermostat
List of things that don't update DST on their own:
1. My Ford cars, each of which cost more than the entire above list combined.
This is inexcusable. I've bought not one, but TWO new Fords in the last four months. Had I known just how bad the design of the electronics was, I'd have gotten a Subaru instead. VERY frustrating!
Its probably because some places do NOT do DST, i.e. Arizona. So its not an issue of "can it" (since at once time it was enabled) but a decision was made to NOT do it, figuring on a pro/con list.
When people through out "This is inexcusable" I sort of chuckle, I mean really? That's pretty strong language/feelings about something that takes 5-10 seconds to remedy, doesn't inhibit the use of the vehicle, and only occurs twice per year.
If it makes you feel better, think of the 20 seconds you lose each year by having to manually go and adjust the clock, and then subtract that by the lack of trips to the gas station. Going to the gas station is a 5-10 minute affair? I'm down from weekly fill ups to every 6 weeks, so that's ~9 trips compared to 52 trips to the gas station. 43 less trips x 5 minutes per trip is 215 minutes!
215 minutes is WAY more then 20 seconds... ;-)
