The new Mercedes Sylvia got is fully electric, and it invites you strongly to install the app on your phone for emphasizing their branding (can do without, but whatever) and ease of use (oh well, I succumbed to this call too).
Terrible behaviour surfaces, quality testing wise. They should have caught this early on.
This is long, feel free to skip.
One feature, slightly more useful (I think) than a washing machine app that alerts you when the thing finishing its washing cycle, is the ability to monitor the charging state while it is, well, charging. And when it is not. Why is that possibly important, since the next charger may be several hundred metres away, out of sight, on a public street where they charge extra hefty fees when you park there and the thing is full or does not charge.
Good feature to have also to not exceed the recommended 80% full by much.
So an iOS app was first to pair with the car. Sylvia used the car, parked it at the charger, started charging, walked to her office and called to tell me. First time users are like that, I am too. :)) I then opened my app, and something happened. Her app stopped updating the charging state. My app did show charging state and progress, but hers did not any more.
It took a version update of her app to "fix", which happened weeks later. No release notes saying "we fixed an annoying bug related to charge-o-metering".
Another issue with the app is, it notifies about the car state. Again, well-intentioned, but... implementation meh.
Lets say, I drive to the scrapyard to orderly dispose of electrical appliances, let the door open because no spare hand, take out the thing from the back seat. Lug over the thing towards the container, door stays open for more than 30 seconds, triggers an (invisible to me) alarm state. I do not know, receive no notification, then got rid of whatever, then drive home. Some 10 minutes later Sylvia's app triggers the alarm "door is open, do something, yes?" with no clear labels on the available buttons either. Terribly useless UI, and the delay of too many minutes means I do not know what she is talking about when she calls to ask "what happened to the car?" at first. Also, she does not get a timestamp of the event sop does not know "something" happened many minutes earlier.
We can smile this away, but quality assurance should have caught this.
We can smile this away, but given quality assurance for a Chinese make of BYD or Beijing motors that comes at half the price would probably mean better software.
We can smile this away, but we can attribute the 40% lower numbers of new Mercedes sold last year may trace back to quality assurance - it should have hjalped to prevent this.
Software must just work and get out of your way. German engineering forgot. Oh well, at least there's physical, tactile buttons for many oft-used features.
The one useful feature of having the app it enables per-user profiles for the in-car system controls and that allows me to switch off or turn to mid-grey all the interior LED blinkenlights. If you don't it feels you're driving around a mobile disco. They kept changing colours all the time, super distracting and depending on whatnot. The off feature is the best thing I've discovered yet.
I like it this way, it intrudes into a space combustion car users may have long thought is untouchable, in a way. Not it isn't, you too are supposed to see change is happening. It practically solves the issue of where the plug is. Park any way you see fit. Carsten Raddatz (@carstenraddatz@pixelfed.automat.click)
