When is my $16 Wall Clock Smarter than my $47,000 Car?

Well it's funny, but yes, they should add time zone support and DST switching.
As most of the infotainment/navigation system is Linux based, this should not be a major problem as you get it out of the box.

 

You go into settings and activate/deactivate the DST button. It will change an hour back/fourth.

Could it be solved with Software? Definitely!

 

Because they sell cars outside Korea and their customers expect DST support.
Also as they base their infotainment on Linux operating system, DST switching support is easy to do as it is built into Linux for decades.

What they need to do is just enable user to select their timezone and the rest can be done through software.

 

Well if the congress ever gets their act together and allows permanent DLST, California, Oregon, Washington state can stop with the biannual clock adjustment.

 

Well, there is already a couple states like Arizona that don't have DST.

So it's not "just" the time zone.

 

I would rather have permanent DST than standard time. I like that extra hour of daylight at the end of the day.
